Bonjour

The ASW (sometimes written as a.s.w. or asw) is the Actual Silver Weight of a coin. The ASW is expressed as a decimal value of one full ounce of silver, so .18084 asw means that the coin has 0.18084 of an ounce of pure silver in it. Here are two examples using a pre-1965 90% silver U.S. Quarter Dollar, with an asw of .18084, a total weight of 6.25 grams, and a fineness of .900:

To determine the coin's actual silver value, multiply the asw by the spot price (for example, if the spot price is $18.35 an ounce, take .18084 x 18.35 = 3.318414, or about $3.32 worth of silver.)

En esperant que tu parles un peu Angliche
