The troy ounce is the standard silver price that you see on the t.v. 1 troy ounce = 31.1034768 grams or 1.09714 U.S. Ounces. It is usually just referred to as an oz.
The silver price is based in troy ounces and that means we need to multiply the metal price by .0321507466 to make the conversion to grams. 1. Calculate 90% silver value : (19.66 Ã .0321507466 Ã 2.5 Ã .90) = $1.4221882758. $1.4221 is the rounded silver value for the 1916-1945 Mercury silver dime on August 18, 2016. This is usually the value used by coin dealers when selling these coins at melt value. However, the total melt value is continued below.
