The weight of a gold coin can vary significantly, ranging from fractional grams to kilograms . However, the most commonly traded and popular size for gold coins is one troy ounce.
Here’s a breakdown of common gold coin weights:
- 1 Troy Ounce: This is the standard size and weighs approximately 31.103 grams.
- Fractional Ounces: Many mints also offer fractional gold coins in sizes like 1/2 oz, 1/4 oz, and 1/10 oz.
– 1/2 oz ≈ 15.55 grams
– 1/4 oz ≈ 7.78 grams
– 1/10 oz ≈ 3.11 grams
- Gram Weights: Some gold coins are measured in grams, especially from certain mints like the Chinese Mint. These can range from 1 gram to 1 kilogram. Examples include:
– 1 gram
– 2 grams
– 8 grams
– 10 grams
– 1 kilogram
- Other Sizes: You can also find gold coins in less common sizes like 2 oz, 5 oz, or even miniature versions.
- The term “ounce” for gold coins typically refers to the troy ounce , which is slightly heavier than the standard (avoirdupois) ounce.
- While 1 troy ounce is the most common, smaller fractional and gram weights are available to accommodate different budgets and investment strategies.
- The overall weight of a gold coin might differ slightly from its pure gold content if it’s an alloy (like a 22k coin with copper) to enhance durability.
