24K gold is nearly pure gold, usually .999 or .9999 fine. 22K gold is 91.67% gold and 8.33% alloy. For the same total weight, 24K has more melt value; for some jewelry and classic bullion coins, 22K can be more durable.
Purity difference
24K gold is the highest common purity category. It is preferred for many investment bars and some sovereign bullion coins.
22K gold is 22 parts gold out of 24, or about 91.67% gold. The rest is alloy metal such as copper or silver.
Durability difference
Pure gold is soft. Alloyed 22K gold can resist wear better, which is why it appears in jewelry and famous bullion coins such as American Gold Eagles and Krugerrands.
A one-ounce 22K bullion coin can still contain one full troy ounce of pure gold, but the coin's total weight is higher because of the alloy metal.
Which is better?
For pure melt value per total gram, 24K wins because more of each gram is gold.
For jewelry wearability or certain coin preferences, 22K can make sense. The better choice depends on whether you care most about purity, durability, premium, recognition, or resale channel.
Common questions

Not always. 24K has higher gold purity, but 22K can be more durable and is used in well-known bullion coins and jewelry markets.
