Which Size Bullion Coin to Choose?
One Ounce Bullion Coins & Others
There is a choice of which size gold bullion coins to buy for investment, but our advice is generally to buy the cheapest (i.e. the lowest premium).
Fractional Bullion Coins
Various Weights of Bullion Coins
Here are the weights of bullion coins commonly available. There are of course others, these are the most readily available:
- One Ounce
- Half Ounce
- Quarter Ounce
- Tenth Ounce
Other weight of gold coins are available, including twentieth ounce, one twenty-fifth of an ounce, two ounces, ten ounces, and one kilo. Often the prices per ounce are extortionate making them an illogical investment but some are collectable and hold numismatic value. In theory, larger coins should be available at lower premiums, but they are not as easy to obtain. Plus the market for them is less liquid, therefore dealers expect bigger margins on them. They are mainly bought as novelty items and if you wanted to use a one coin as a doorstop you could do!
Over many years, our advice to investors has been very simple and consistent. Within reason, buy the cheapest, by which we mean the lowest percentage premium over gold.
Most of the time, one ounce bullion coins sell at lower percentage premiums than their fractional equivalents, full one ounce bullion coins are therefore a better investment purchase than the fractional weights.
It is often possible to buy older "real" gold coins, including smaller ones, for a premium similar to one ounce bullion coins. In that case, we would obviously recommend buying them instead. More information on our Real Coins versus Bullion Coins page.
