Are Fractional Gold Coins Worth It?

Short answer: fractional coins let you buy small amounts and sell in small steps, but they carry a higher premium per gram than one-ounce coins and larger bars. They make sense when flexibility matters more than the lowest cost per gram.

Why the premium is higher

Minting, packaging and distribution cost roughly the same per coin whatever its size, so on a smaller coin that cost is spread over less metal. A tenth-ounce coin therefore costs more per gram than a one-ounce coin. See fractional coin.

Measure the extra cost

Work out the premium of each size against its melt value with the premium over spot calculator, and compare the cost per gram of fine gold. The difference is the price of flexibility.

When they make sense

• You want to build a position with small, regular amounts.
• You might need to sell part of your holding without selling it all.
• You value a recognisable coin for gifts or small trades.

When larger sizes are better

If you are buying a large amount and will hold it for a long time, larger coins or bars usually give you more metal for your money. Many people mix sizes.

Record the size and weight

Track fine weight and total cost for each coin, so your cost per gram shows how much the size choice has cost you.
