How the melt value is worked out
Melt value is the pure silver in the coin multiplied by the spot price. We use the coin's standard minted weight; worn coins weigh slightly less.
-
5.832 g × .9167 fine ÷ 31.1035 g per troy oz = 0.1719 troy oz
0.1719 troy oz × $54.05 spot = $9.29
Melt value vs. collector value
Melt value is a floor, not a price. Better dates, coins with mint luster and graded coins often sell well above melt; key dates and rare varieties can be worth many times more. Check the date and mint mark before selling a coin for its metal.
