Melt is the metal only. It ignores collector (numismatic) value, which can be far higher for scarce dates, high grades or certified coins. It's also not what you'll be paid: dealers usually buy below melt to cover refining and their margin, and sell above it. Use melt as a floor-of-metal reference, not a price.

FAQ
1.0000 troy ounces of pure gold (31.103 g). That figure comes from the official specification cited on this page, not from weighing a coin.
Multiply its fine gold content (1.0000 troy oz) by the gold spot price per troy ounce. At $4,179/oz that comes to $4,179 per coin. For several coins, multiply by the count.
Usually not quite. Dealers typically pay somewhat below melt for common bullion and junk silver to cover refining, shipping and their margin. Coins with collector value can sell well above melt, so check a coin's date, mint mark and condition before selling it as metal.
