@Space22: To pick a nit, the coin does not have a full quarter ounce of gold.
With a weight of 8.359 grams of 0.900 fine gold, it contains 7.523 grams of pure gold. As a troy ounce weighs 31.1 grams, the US $5.00 gold coin contains (7.523 g / 31.1 g) or 0.2419 troy ounces of gold - just under a quarter ounce.
