How Much Do Gold Coins Weigh?

Gold coins come in various purities, typically denoted in karats (k), where 24k gold signifies pure gold. A coin’s purity is crucial because it affects the coin’s weight. Pure gold is often too soft for practical use, so gold coins often contain other metals, such as silver, copper, or zinc, for added strength and durability.

For instance, American Eagle Gold Coins, one of the most widely traded gold bullion coins globally, consist of 22k gold. Although it contains one troy ounce of pure gold, the coin weighs slightly over a troy ounce due to the additional alloyed metals.

An Overview of Gold Coin Weights

Gold coins are available in various sizes, each with different weights. Some commonly traded gold coins and their weights include:

American Eagle Gold Coin: 

Available in 1/10, 1/4, 1/2, and 1 troy-ounce denominations, containing 91.67% gold.

Canadian Maple Leaf: 

Comes in 1/20, 1/10, 1/4, 1/2, and 1 troy-ounce sizes, made of 99.99% gold.

South African Krugerrand: 

Available in 1/10, 1/4, 1/2, and 1 troy-ounce denomination, comprising 91.67% gold.

Australian Gold Kangaroo/Nugget: 

Comes in 1/20, 1/10, 1/4, 1/2, 1, 2, and 1-kilogram sizes, made of 99.99% gold.

Note that when these coins are referred to by their weight, it refers to the weight of the gold content only, not the weight of the coin itself if it’s not pure gold.

Is Gold Heavier Than Silver?

Gold is indeed denser and heavier than silver. Pure gold has a density of 19.32 grams per cubic centimeter (g/cm³), while silver has a density of 10.49 g/cm³. However, the weights of gold and silver coins can be the same, depending on their sizes.

Troy Ounce vs. Regular Ounce

When dealing with precious metals, weights are typically given in troy ounces. A troy ounce is a measure used for weighing precious metals that dates back to the Middle Ages.

One troy ounce is equivalent to 31.1035 grams, more than the regular or avoirdupois ounce used in the US, equivalent to 28.3495 grams. Remembering this difference when buying, selling, or trading gold coins is crucial.

Gold Coins are Measured in Troy Ounces

As noted, gold coins are measured in troy ounces. This tradition originates from the Middle Ages when the Troy system was employed for weighing precious metals and gemstones. Today, all precious metals, including gold, are sold worldwide in the troy weight system.

How Much Does a 24k Gold Coin Weigh?

A 24k gold coin refers to a coin made of pure gold. The weight of a 24k gold coin can vary depending on its size. For example, a 1 troy ounce 24k gold coin weighs exactly one troy ounce, 31.1035 grams.

How Much Does a Gold Coin Weigh in Grams?

The weight of a gold coin in grams depends on the coin’s size and purity. For example, a 1-troy-ounce pure gold coin weighs 31.1035 grams. However, if the coin is of lesser purity, say 22k, like the American Gold Eagle, it would contain 31.1035 grams of pure gold but weigh slightly more due to the additional alloyed metals.

In conclusion, understanding the weights of gold coins and the difference between troy and regular ounces is crucial for investors and collectors. It helps ensure accurate and fair transactions, allowing individuals to build a valuable and secure gold portfolio.
