The weight and diameter of gold pieces vary depending on the size of the coin. A one ounce gold coin is heavier than a traditional ounce, containing approximately 31.1 grams. This means that a single troy ounce of gold would look like a plate about the length of a pen clip. For example, the Perth Mint produces minted (1 ounce) gold ingots known as Kangaroo gold bars, which are popular with Americans.
The 1-ounce American gold eagle is an iconic and highly sought-after gold coin that has been treasured by collectors and investors alike for decades.
