Yes, but only coins dated 2013 or later: that year the Gold Britannia went from 22 karat (.917) to .9999 fine gold, above the .995 floor in 26 U.S.C. 408(m)(3)(B). "IRA-eligible" means an IRA can buy the coin without the purchase being taxed as a withdrawal. A 22-karat coin is 22 parts gold in 24, or 91.7%. A .9999 fine coin is 99.99% gold. Older Britannias look almost the same and hold the same ounce of gold, so how does a buyer keep one out of an IRA?
The law is only half of the answer. Your custodian's list and your dealer's shipping habits decide whether the right year arrives. As of September 29, 2026, a random-year 1 oz Britannia cost 2.57% over its gold value at SD Bullion, a large online dealer. The Britannia is one of the coins checked in our database of IRA-eligible precious metals.
The sections below cover the years that qualify, the 2013 purity change, the 8 sizes, custodian wording, the random-year trap, 2026 costs and the Gold Eagle comparison.
Which Gold Britannia Years Are IRA-Eligible?#
Gold Britannias dated 2013 or later are IRA-eligible because they are .9999 fine; those dated 1987 to 2012 are .917 fine and are not. The date on the coin decides. Fineness is the share of pure gold, written as a decimal: .995 means 99.5% gold.
The test comes from the bullion clause of the tax code. Bullion is metal valued for its weight, not its rarity. The clause lets an IRA hold gold of at least .995 fineness while a trustee holds it (26 U.S.C. 408(m)(3)(B)). A custodian is the trust company that holds your IRA and approves each purchase. The table below sets the 2 date ranges against that test.
| Dated | Fineness | Passes the .995 test? | IRA-eligible? | Custodian wording (lists read September 29, 2026) |
|---|---|---|---|---|
| 1987 to 2012 | .917 (22 karat) | No | No | STRATA and GoldStar: "British Britannia (pre-2013)" unacceptable |
| 2013 and later | .9999 ("999.9") | Yes | Yes, while a trustee holds it | STRATA and GoldStar: "British Britannia (2013 and newer)"; Equity Trust: "British Britannia coins (.9999+)" |

Why does one year make the difference? The same test decides every coin on the list of IRA-approved precious metals.
The Gold Britannia Changed From .917 to .9999 Fine Gold in 2013#
The Royal Mint struck the Gold Britannia in 22-karat gold (.917 fine) from 1987 through 2012 and in .9999 fine gold from 2013. The Mint says so on its own page for the 1 oz coin: "Upon its release, the gold Britannia coin was struck in 22 carat gold." It then adds: "The Royal Mint increased the coin's purity to 24 carat gold in 2013".
UK law fixes the purity by royal proclamation, the legal notice that sets a coin's weight, size and gold content. The proclamation published October 19, 2012 gives the new £100 coin "a millesimal fineness of not less than 999.9". Millesimal fineness counts parts of pure gold per 1,000, so 999.9 equals .9999.
The US side is one sentence of the tax code. An IRA may hold gold bullion "of a fineness equal to or exceeding the minimum fineness that a contract market ... requires" (26 U.S.C. 408(m)(3)(B)). A contract market is a regulated futures exchange, such as COMEX. The COMEX gold contract requires "a minimum of 995 fineness" (Rule 113101).
The .995, .999 and .9995 thresholds are explained on gold IRA purity requirements. Neither the Mint's page nor the statute puts the 2 histories side by side. The 5 dates below do.
- 1987: first Gold Britannia, 22 karat (.917). No foreign coin is allowed in an IRA.
- 1998: bullion clause in force for tax years beginning after December 31, 1997 (Pub. L. 105-34, sec. 304). Gold of .995 is allowed. The Britannia is still 22 karat and still fails.
- October 2012: proclamation published for a £100 coin of "not less than 999.9".
- 2013: first .9999 Britannias. These are the first Britannias an IRA can hold.
- 2015, 2017, 2021: proclamations published June 19, 2015, October 13, 2017 and November 12, 2021 repeat "not less than 999.9".
The Britannia became IRA-eligible 15 years after the law opened the door to .995 gold. A 22-karat coin (.9167) misses that floor by 78.3 parts per thousand. It reaches 92.1% of the required purity.
Why a 22-Karat Britannia Fails When a 22-Karat Gold Eagle Passes#
Because US law names the American Gold Eagle and names no British coin: the Eagle is eligible whatever its purity, while every foreign coin must pass the .995 test. A named coin is a coin the tax code lists by pointing to the US coinage law. For gold, the code names only "a gold coin described in paragraph (7), (8), (9), or (10) of section 5112(a) of title 31" (26 U.S.C. 408(m)(3)(A)(i)). Those 4 paragraphs describe the 4 sizes of the Gold Eagle. Why a 22-karat US coin qualifies is explained on American Gold Eagle in an IRA.
The old Britannia is not short of gold. According to dealer specifications, the pre-2013 1 oz coin weighs 34.050 grams in total. At 22 karat, that works out to 31.21 grams of gold plus 2.84 grams of alloy, the other metal mixed in to harden the coin. A pre-2013 1 oz Britannia holds the same ounce of gold as a new one. It fails on the ratio of gold to alloy, not on the amount of gold. The same rule keeps out the Krugerrand and the Sovereign. Coins outside both exceptions fall under the IRS collectibles rule.
How to Tell a 2013-and-Later Britannia From an Older One#
The date on the coin settles it: a Gold Britannia dated 2013 or later is .9999 fine, and one dated 1987 to 2012 is 22 karat. Check 3 things, in the order below.
- Read the date on the coin. A date of 2013 or later passes.
- Look for "999.9" on the Britannia side. Proclamations published from October 2013 onward put the figure on the coin, for example "1 OZ FINE GOLD 999.9 2015 BRITANNIA" (2015) and "1OZ 999.9 BRITANNIA FINE GOLD" (2021). A coin with "999.9" is never the 22-karat coin.
- Ask the dealer to put the year and ".9999" on the invoice. Your custodian sees the invoice, not the coin.
The purity stamp has one gap. The inscription in the proclamation published October 19, 2012 carries no "999.9". So for a coin without the figure, the date is the only test.
Portraits are not a test either. Queen Elizabeth II appears on both 22-karat and .9999 coins. Coins that show King Charles III are all dated after 2013, so all are .9999. The Mint also says new security features "enhanced our Britannia bullion coins" in 2021 and 2022. A Royal Mint press release names 4 of them. They are a latent image that shifts from a padlock to a trident, a moving wave pattern, the micro-text "DECUS ET TUTAMEN" and tincture lines (fine background lines). Coins that show them are dated 2021 or later, so they are .9999.
What Are the Gold Britannia's Sizes and Specifications?#
The .9999 Gold Britannia comes in 8 sizes, from a 5 oz coin (£500 face value) to a 1/40 oz coin (50p), each fixed by royal proclamation. A troy ounce is 31.1035 grams, the unit used for precious metals. Face value is the amount stamped on the coin in pounds, far below its gold value. Standard weight is the target weight the Mint must hit, within a small allowed margin called the remedy. The table lists 7 sizes; the eighth is the 2 oz coin in the note below it.
| Size | Face value | Standard weight | Diameter | Fineness | Fine gold at standard weight (computed, troy oz) |
|---|---|---|---|---|---|
| 5 oz | £500 | 156.295 g | 50 mm (65 mm in the 2013 and 2014 proclamations) | 999.9 | 5.0245 |
| 1 oz | £100 | 31.21 g | 32.69 mm (38.61 mm in the proclamations published October 2012 and May 2013) | 999.9 | 1.0033 |
| 1/2 oz | £50 | 15.6 g | 27 mm | 999.9 | 0.5015 |
| 1/4 oz | £25 | 7.8 g | 22 mm | 999.9 | 0.2508 |
| 1/10 oz | £10 | 3.13 g | 16.5 mm | 999.9 | 0.1006 |
| 1/20 oz | £1 | 1.58 g | 12 mm | 999.9 | 0.0508 |
| 1/40 oz | 50p | 0.8 g | 8 mm | 999.9 | 0.0257 |
Source: royal proclamations in The Gazette (published June 19, 2015 and November 12, 2021; earlier widths from the proclamations published October 19, 2012, May 17, 2013 and June 13, 2014). Fine gold computed: standard weight × 0.9999 ÷ 31.1035. The 2 oz coin (£200, 62.42 g, 40 mm) appears in the 2021 proclamation only.
The 1 oz coin's standard weight is 31.21 grams, with a remedy of 0.15 grams. Its fine gold at standard weight is 0.33% above one troy ounce. Dealers and custodians still price and value the coin as 1 oz of gold.
The £100 face value does not make the coin money in the US. Foreign coins "are not legal tender for debts" (31 U.S.C. 5103). Legal tender status is not a reason for IRA eligibility either: the test is fineness.
The 5 oz and 1/20 oz Gold Britannia Sizes Were Added in 2013#
In 2013 a royal proclamation added two Gold Britannia sizes: a 5 oz coin (£500 face value, 156.295 grams) and a 1/20 oz coin (£1 face value, 1.58 grams). The proclamation published in The London Gazette on May 17, 2013 sets each coin's weight, width and purity. It is the earliest notice we found that lists either size. Both coins carry "a millesimal fineness of not less than 999.9".
Reference pages often give other figures for these coins. The table sets the common figures against the proclamations.
| Detail | Common figure | Proclamation figure | Fine gold (computed) |
|---|---|---|---|
| 1/20 oz face value | £5 (also seen: 50p) | £1 in every proclamation read, 2013 to 2021 | 0.0508 troy oz |
| 5 oz diameter | 65 mm | 65 mm in the 2013 and 2014 proclamations; 50 mm in 2015 and 2021 | 5.0245 troy oz |
| 1/40 oz (added later) | Confused with the 1/20 oz coin | 50p, 0.8 g, 8 mm; first listed in the proclamation published June 13, 2014 | 0.0257 troy oz |
Sources: royal proclamations published May 17, 2013, October 11, 2013, June 13, 2014, June 19, 2015 and November 12, 2021.
So the widely copied £5 face value is wrong, and the 65 mm width is out of date. The 50p value belongs to the 1/40 oz coin.
Both sizes clear the purity test, but neither is a standard IRA choice, for 2 reasons. First, dealer catalogs list the 2013 coins in both sizes as proof issues. A proof is a collector version struck with a mirror finish and sold in a box with a certificate. GoldStar Trust takes proofs only "ungraded, complete with certificate of authenticity and in original mint packaging".
Second, small coins cost more per ounce. At one large dealer on September 29, 2026, a 1/10 oz Gold Maple Leaf cost 14.92% over its gold value, against 3.10% for the 1 oz coin. We captured no price for a fractional Britannia that day. Packaging and price rules for proof coins in an IRA apply to these sizes.
Which Britannia Sizes and Versions Make Sense in an IRA?#
For an IRA, the plain 1 oz bullion Britannia dated 2013 or later is the version every custodian list we read names. The 3 groups below run from the simplest choice to the riskiest.
- 1 oz bullion coin, 2013 or later: named on all 3 large custodian lists read on September 29, 2026. It is also the size dealers quote and buy back.
- Fractional bullion coins (1/2, 1/4 and 1/10 oz): .9999 fine and eligible. The custodian lists do not limit size. Ask for the price per ounce first.
- Proof, graded and privy-mark issues: proofs only in original packaging with the certificate. GoldStar and Equity Trust do not take graded coins.
Sizes and premiums for all IRA-eligible gold coins are compared on the group page.
Which Custodians Accept the Gold Britannia?#
All 3 large custodians we checked accept Gold Britannias dated 2013 or later, but 1 other custodian's form lists the Britannia as unacceptable with no year. Two of the 3 large custodians, STRATA and GoldStar, also list the pre-2013 coin by name as unacceptable. STRATA wants bullion coins "in brilliant uncirculated condition and free from damage". Brilliant uncirculated means new condition, never used as money. The tables quote each list as read on September 29, 2026.
| List | 2013 and later | 1987 to 2012 | Exact wording |
|---|---|---|---|
| STRATA Trust | Yes | No | "British Britannia (2013 and newer)"; "British Britannia (pre-2013)" unacceptable |
| GoldStar Trust (page dated April 3, 2026) | Yes | No | "British Britannia (2013 and newer)"; "British Britannia (pre-2013)" unacceptable |
| Equity Trust (page dated June 1, 2026) | Yes | Not listed | "British Britannia coins (.9999+)" |
| Directed IRA (Directed Trust Company, Direction of Investment form, 2025) | Listed as unacceptable, no year given | Listed as unacceptable | "UNACCEPTABLE PRECIOUS METALS INCLUDE: ... British Britannia ..." |
| Gainesville Coins IRA page (a dealer, for contrast) | Listed as unacceptable, no year given | Listed as unacceptable | "British Britannia" |
| Version | STRATA Trust | GoldStar Trust | Equity Trust |
|---|---|---|---|
| Proof Britannia, original box and certificate | Proof rule applies | Proof rule applies | Not addressed: ask in writing |
| Graded or slabbed Britannia | "Any rare or collectible coin" excluded | No: "certified or 'graded' coins" | No: slabbed coins "are not acceptable in IRAs at this time" |
Custodian policy is contract terms, not tax law, but a coin your custodian's list rejects cannot settle into your IRA.
A graded or slabbed coin is sealed in a plastic holder by a grading company with a score. No list we read names proof Britannias, so the general proof rules apply.
The disagreement between the lists is the finding. A list written before 2013 was right at the time, because every Britannia was then 22 karat. A list not updated since is out of date, yet it still binds that custodian's customers.
Fees and product rules for all the gold IRA custodians we profile sit side by side.
The Random-Year Trap: How an IRA Order Can Deliver a 22-Karat Coin#
A "random year" Gold Britannia order lets the dealer choose the date, so the order must say "2013 or later, .9999" or a 22-karat coin can arrive. Random year means the dealer picks which date to ship, often at the dealer's lowest price. Dealers also call it "varied years" or "date our choice". The lowest Britannia price we captured on September 29, 2026 was SD Bullion's "1 oz Gold Britannia Coin, Random Year".
We found no record that any named dealer shipped a wrong-year Britannia to an IRA. Sellers know the rule. The eligible-metals list at sbcgold.com, an IRA seller, said on October 2, 2026: "Gold & silver Britannias minted before to 2013 are ineligible". So the risk sits in the wording of the listing, and 3 kinds of wording matter.
- Random-year listings: the lowest price, with the date left to the dealer.
- Listings that state ".9999": safe on purity, because only 2013-and-later coins are .9999.
- "IRA-approved" category labels: a dealer's label, not a custodian's decision. On September 29, 2026, SD Bullion's "IRA approved gold" category included a proof Gold Buffalo, a coin GoldStar lists as unacceptable.
A coin your order did not exclude is a coin the dealer may ship. The pre-2013 Britannia sits on our list of coins and bars you cannot hold in an IRA.
What If a Pre-2013 Britannia Was Delivered to Your IRA?#
The tax code treats an IRA's purchase of a 22-karat Britannia as a withdrawal equal to the coin's cost, taxed in the year of purchase. The coin counts as a collectible, an item an IRA cannot buy without tax.
IRS Publication 590-A (2025) adds that the amount taxed at purchase is not taxed again when the coin is later distributed. The example below assumes a traditional IRA, the 22% federal bracket, an owner aged 57 and federal tax only.
| Step | Amount |
|---|---|
| Coins ordered | 10, random year |
| Price per coin (SD Bullion wire price, September 29, 2026) | $4,260.68 |
| Coins dated before 2013 | 3 |
| Amount treated as a withdrawal | $12,782.04 |
| Federal income tax at 22% | $2,812.05 |
| 10% additional tax, under age 59 1/2 | $1,278.20 |
| Total federal cost | $4,090.25 |
Worked example with stated assumptions; not a forecast and not tax advice.
Three wrong coins cost $4,090.25, and the coins still sit in the vault. Two steps can stop the problem before it starts.
- Ask the custodian or depository to check dates before the metal is booked into your account, and to reject wrong-year coins.
- Ask the dealer in writing to replace any coin dated before 2013 before settlement.
The same math, with a larger example, is worked through for Krugerrands in an IRA.
How Much Does a Gold Britannia Cost Over Spot in 2026?#
As of September 29, 2026, a random-year 1 oz Gold Britannia cost 2.57% over its gold value at a large online dealer, less than a Gold Eagle (3.03%). It cost slightly more than a Philharmonic (2.03%). The dealer is SD Bullion, and the prices are its wire prices.
Spot price is the market price of 1 troy ounce of gold at that moment. Melt value is the coin's gold content times the spot price. Premium over spot is what you pay above the melt value, as a percent of it. The table ranks eight 1 oz coins by premium.
| Coin (1 oz) | Price | Gold value (melt) | Premium | Read from |
|---|---|---|---|---|
| Australian Kangaroo (random year) | $4,240.68 | $4,156.82 | 2.02% | C |
| Austrian Philharmonic (random year) | $4,241.37 | $4,156.82 | 2.03% | C |
| Chinese Panda (random year, pre-2016) | $4,251.14 | $4,153.88 | 2.34% | P |
| British Britannia (random year) | $4,260.68 | $4,153.88 | 2.57% | P |
| American Gold Eagle (random year) | $4,280.53 | $4,154.51 | 3.03% | P |
| Canadian Maple Leaf (random year) | $4,282.45 | $4,153.88 | 3.10% | P |
| Mexican Libertad (2024) | $4,332.46 | $4,156.82 | 4.23% | C |
| American Gold Buffalo (random year) | $4,391.80 | $4,154.51 | 5.71% | P |
SD Bullion, September 29, 2026: one dealer, one morning; wire prices. P = product page, C = category listing (more risk of mismatch).
In dollars, $50,000 bought 11.735 Britannias or 11.681 Gold Eagles that morning. The gap is 0.054 of a coin, about $226 more gold. A second dealer shows the same direction. Fisher Precious Metals' price sheet, effective September 28, 2026, adds $149 per Britannia and $204 per older-date Gold Eagle for 1 to 9 coins. At 10 to 19 coins the figures are $139 and $194. At 20 or more they are $129 and $184, so the $55 gap holds at every order size. Fisher prices from the COMEX spot price.
This is one dealer on one morning, and premiums move daily. The low price sits in random-year stock, which is why the year instruction matters. Premium over spot is only one of the gold IRA markups and spreads a buyer pays.
Round-Trip Cost: What You Get When You Sell#
Buying a 1 oz Gold Britannia and selling it back the same day cost 5.89% on September 29, 2026, against 5.39% for a Gold Eagle. The reason is the bid: the dealer paid $40 less for a Britannia than for an Eagle.
The ask is what you pay the dealer. The bid is what the dealer pays you. The round trip is what you lose when you buy and sell back at once. Break-even is the rise in price you need to get your money back. The table shows SD Bullion's ask and bid for 4 coins at about 10:20 UTC.
| Coin (1 oz, random year) | Ask | Bid | Round-trip loss | Rise needed to break even |
|---|---|---|---|---|
| Australian Kangaroo | $4,240.68 | $4,019.93 | 5.21% | 5.49% |
| Austrian Philharmonic | $4,241.37 | $4,019.93 | 5.22% | 5.51% |
| American Gold Eagle | $4,280.53 | $4,049.93 | 5.39% | 5.69% |
| British Britannia | $4,260.68 | $4,009.93 | 5.89% | 6.25% |
Single dealer, single morning (SD Bullion, September 29, 2026). Bids come from a sell page that may lag the live market.
The Britannia was cheaper to buy and dearer to sell. It cost $19.85 less than the Eagle and returned $40.00 less, so the round trip was $20.15 worse per coin. Against the Philharmonic it was $29.31 worse. The Britannia bid of $4,009.93 equaled the dealer's bid for a generic 1 oz gold bar.
Fisher's sheet points the same way. Its sell-to-us price was "-4.5%" for British 1 oz coins and "-3%" for the American Eagle, effective September 28, 2026. Run your own quote and bid through the gold IRA break-even calculator.
Gold Britannia, Gold Eagle or Another .9999 Coin: Which Fits Your IRA?#
The 2013-and-later 1 oz Britannia is a low-premium way to hold .9999 gold in an IRA, but it sold back for less than a Gold Eagle on September 29, 2026. The right coin depends on your situation, so the table gives a verdict for 7 of them.
| If you... | Better fit | Why |
|---|---|---|
| Want a low purchase premium and accept a lower resale bid | 1 oz Britannia, 2013 or later | 2.57% premium, $4,009.93 bid (SD Bullion, September 29, 2026) |
| Want the best resale bid at that dealer on that day | American Gold Eagle | $4,049.93 bid, $40 above the Britannia |
| Want the lowest round-trip cost | Kangaroo or Philharmonic | 5.21% and 5.22% round trip, against 5.89% |
| Have a custodian whose list is silent or lists the Britannia as unacceptable | A coin the list names, or written approval first | Directed Trust Company's 2025 form lists "British Britannia" with no year |
| Are offered a random-year Britannia | Accept only with "2013 or later, .9999" on the invoice | The dealer picks the date |
| Are offered proof, graded or "limited" Britannias | Ask for the price per coin and the buyback bid in writing | GoldStar and Equity Trust do not take graded coins. These coins are the usual vehicle for numismatic coin upsells |
| Already own Britannias at home | You cannot contribute them | IRA contributions must be cash (26 U.S.C. 408(a)(1)) |
Prices and bids: SD Bullion, September 29, 2026. Custodian lists read the same day.
Is the Gold Britannia a good investment? This page cannot answer that for you, and it makes no price forecast. What the dated numbers show is narrower. The coin's gold is worth the same as any other .9999 ounce. The cost difference lies in the premium you pay and the bid you get back. You should compare both numbers before you choose.
How Does the Gold Britannia Fit Into the Rest of a Gold IRA?#
The date on the coin settles only whether an IRA may buy a Gold Britannia; the account rules on custody, statements and withdrawals decide what happens after that. A gold IRA is an IRA that holds physical metal through a custodian. How a gold IRA works from opening to withdrawal is explained step by step. Custody, statements and withdrawals follow the gold IRA rules for every coin, the Britannia included.
Is the Silver Britannia IRA-Eligible Too?#
Yes, with the same cut-off: silver Britannias dated 2013 or later are .999 fine and pass, while those dated 1997 to 2012 fail. The older silver coins are .958 fine, below the .999 floor for silver. The Royal Mint says silver purity "increased from 0.958 to 0.999 fineness" in 2013. Prices and the .958 history are covered on British Silver Britannia in an IRA.
Can You Keep IRA Britannias at Home or Add Coins You Already Own?#
No to both: the bullion clause covers gold only while a trustee holds it, and IRA contributions must be made in cash. A trustee is the bank or trust company that legally holds the IRA's assets. The clause applies only to bullion "in the physical possession of a trustee" (26 U.S.C. 408(m)(3)(B)). In McNulty v. Commissioner, 157 T.C. No. 10 (2021), the US Tax Court ruled that IRA coins kept in a home safe were a taxable distribution. Every home storage gold IRA pitch fails the same custody test.
A contribution is new money you put into the IRA, and it must be cash (26 U.S.C. 408(a)(1)). So Britannias you already own cannot be deposited, whatever their date. The 2026 limit is $7,500, plus $1,100 at age 50 and over (IRS Notice 2025-67). Cash deposits count against the gold IRA contribution limits for the year.
Why Your Statement Shows Less Than You Paid for Britannias#
Your first statement values Britannias at the gold price, not at what you paid. At the gold price on the morning of September 29, 2026, $100,000 of coins would show about $97,493. The 3 lines below use SD Bullion's prices from that morning.
- $100,000 at $4,260.68 per coin buys 23.470 ounces.
- At a gold value of $4,153.88 per ounce, the melt value is $97,493.
- At the same-day bid of $4,009.93, a sale returns $94,115, which is 5.9% below cost.
Equity Trust's disclosure says statement values do "not include any markups, commissions or premiums". The same valuation applies when coins leave the account as gold IRA distributions.
Is the Gold Britannia "IRS-Approved"?#
No: the IRS keeps no list of approved coins, so no Britannia is "IRS-approved". The 2013-and-later coin is IRA-eligible because it meets the fineness test in the statute. The IRS says so itself: "there is no list of approved investments for retirement plans" (IRS Retirement Plan Investments FAQs, updated April 8, 2026). A seller's "IRS-approved" label is a sales phrase, not a ruling.
Which Other 22-Karat Gold Coins Fail the IRA Test?#
The South African Krugerrand and the British Sovereign are both .9167 fine and fail the same test as the pre-2013 Britannia. STRATA Trust lists both as unacceptable. The American Gold Eagle is the only 22-karat gold coin an IRA can hold, because the tax code names it. Why Gold Sovereigns fail is explained with the Royal Mint's own specification.
