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.

The Choices
The weights of bullion coins are the most readily available, although there are others.

• One Ounce
• Half Ounce
• Quarter Ounce
• Tenth Ounce

Other Weights
Other weight of gold coins are available, including twentieth ounce, one twenty-fith of an ounce, two ounces, ten ounces, and one kilo.
The price of the tiniest weights makes them a ridiculous investment. In theory, larger coins should be available at lower premiums, but they are not as easy to obtain, and the market for them is less liquid, therefore dealers expect bigger margins on them. They are mainly bought as novelty items. Actually One Kilo gold coins make great paperweights!

Our Advice
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.

Conclusion
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.

However...
It is often possible to buy older "real" gold coins, including smaller ones, for a premium similar to one ounce bullion coins, in which case, we would normally recommend buying them instead. More information on our Real Coins versus Bullion Coins page.
