It appears there may be a misunderstanding about the weight of the gold coin you are referring to. The common weights for American Gold Eagle coins, for example, include 1 oz, 1/2 oz, 1/4 oz, and 1/10 oz . A gold coin with a weight of 1/10 oz is 16.5 mm in diameter and 1.26 mm thick.
It’s possible you’re thinking of a different coin or a typo might have occurred. It’s recommended to double-check the information to ensure accuracy. If you are interested in a specific large gold coin, please provide the name of the coin for more precise information.
However, if you meant to inquire about the largest gold coin ever minted, according to the Guinness World Records, it is the Australian Kangaroo One Tonne Gold Coin . This massive coin has a diameter of 80 centimeters and is 12 centimeters thick. It’s worth over $57 million based on its pure metal content.
