Fractional Gold Coins: 1/10, 1/4 & 1/2 oz Guide (2026)
Fractional gold coins are sovereign coins containing less than a full troy ounce of gold — most commonly 1/2 oz, 1/4 oz and 1/10 oz. At a spot price of $4,059 per ounce (15 July 2026), their melt values are roughly $2,030, $1,015 and $406 respectively, before premium. They're the most affordable way into recognised gold, and the most divisible — but they carry the highest cost per gram in bullion. This guide gives the exact specs, the real premium data, and who each fraction actually suits.
What is a fractional gold coin?
A fractional gold coin is a sovereign-minted bullion coin containing a fraction of a troy ounce of gold — typically 1/2, 1/4 or 1/10 oz. It carries the same government backing, recognised design and guaranteed weight as its one-ounce counterpart, just in a smaller, cheaper unit. Fractionals exist to make gold affordable and divisible.
How much is a 1/10, 1/4 or 1/2 oz gold coin worth?
At a gold spot price of $4,059 per troy ounce (15 July 2026), a 1/10 oz coin holds about $406 of gold, a 1/4 oz about $1,015, and a 1/2 oz about $2,030. Those are melt values — the actual purchase price adds a premium, which is proportionally largest on the smallest coin.
| Coin | Fine gold | Melt at $4,059/oz | Typical premium |
|---|---|---|---|
| 1/10 oz | 3.11035 g | ~$406 | ~8–12% |
| 1/4 oz | 7.77587 g | ~$1,015 | ~6–10% |
| 1/2 oz | 15.55174 g | ~$2,030 | ~4–7% |
| 1 oz | 31.10348 g | ~$4,059 | ~3–5% |
Why are fractional gold coins more expensive per gram?
Retail premiums land above the Mint's wholesale figures — commonly 8–12% on a 1/10 oz Eagle versus 4–6% on the one-ounce. Ten 1/10 oz coins therefore cost meaningfully more than a single 1 oz coin for exactly the same gold.
| Gold Eagle size | US Mint wholesale markup |
|---|---|
| 1 oz | 3% |
| 1/2 oz | 5% |
| 1/4 oz | 7% |
| 1/10 oz | 9% |
What are the exact weights of fractional gold coins?
A 1/10 oz coin contains 3.11035 g of fine gold, a 1/4 oz 7.77587 g, and a 1/2 oz 15.55174 g. Note the difference between fine and gross weight: the American Gold Eagle and the Krugerrand are both 22 carat (91.67%), so they weigh more overall — a 1/10 oz of either has a gross weight of 3.393 g but still holds a full 1/10 oz of gold.
| Coin | Purity | 1/10 oz gross weight | Fine gold |
|---|---|---|---|
| American Gold Eagle | 22k (91.67%) | 3.393 g | 3.11035 g |
| Krugerrand | 22k (91.67%) | 3.393 g | 3.11035 g |
| Britannia / Maple Leaf | 999.9 | 3.11035 g | 3.11035 g |
| Philharmonic / Kangaroo | 999.9 | 3.11035 g | 3.11035 g |
Which coins come in fractional sizes?
The major sovereign bullion coins nearly all offer fractions. The American Gold Eagle and Krugerrand come in 1 oz, 1/2, 1/4 and 1/10. The Britannia, Maple Leaf, Vienna Philharmonic, Australian Kangaroo and Perth Mint's Lunar series also offer fractional sizes. Stick to these recognised names — they resell fastest anywhere in the world.
Are fractional gold coins worth it?
Fractional coins are worth it if you value affordability and divisibility over cost per gram — and not if you're optimising purely for metal per dollar. They let you start with a few hundred dollars, make natural gifts, and let you sell only what you need rather than liquidating a whole ounce. The honest trade-off is that you pay the highest premium in bullion for that flexibility.
- Good for: small budgets, regular monthly buying, gifting, and being able to sell in small amounts
- Less good for: maximising gold per dollar — a 1 oz coin or a 100g bar is far cheaper per gram
- The compromise: the 1/2 oz gives you meaningful divisibility at a premium much closer to a full ounce
