Yes, some gold coins are classed as “Fine Gold” (99.999% gold) meaning they are solid 24ct pure gold.
Many other gold coins have base metals added to them and are 22ct gold (91.67% pure).
This is because pure (24ct) gold is very soft and a coin made with pure gold that was originally in circulation as legal tender would easily be damaged.
The added metals are harder than gold and make the coin more durable and robust.
A “Fine Gold” 24ct bullion coin like the Britannia, Maple, or Buffalo is 1oz in weight, and weights 1oz since there are no base metals added, it is a pure gold coin.
A 22ct (91.67% purity) gold coin like a 1oz Krugerrand will contain 1oz of gold, and 0.9oz of base metal, giving a total weight of 1.09oz.
