I've actually used it a few years ago to carry One Ounce Coins... But I just came up with an improved version... I've been known to invent new products... You're going to love the New Product Line of "Circulating" Silver and Gold Coins I came up with... I'm sure you'll like the New 1/5 Ounce $2 Silver Coin and the New 1/5 Ounce $20 Gold Coin...
