How the melt value is worked out
Melt value is the pure gold in the coin multiplied by the spot price. We use the coin's standard minted weight; worn coins weigh slightly less.
-
31.104 g × .9999 fine ÷ 31.1035 g per troy oz = 0.9999 troy oz (the issuer states 1.0000 troy oz, which we use)
1.0000 troy oz × $3,996.90 spot = $3,996.90
How to identify it
- Britannia with trident and shield on the reverse.

Melt value vs. collector value
Bullion coins usually sell for a premium over melt value. Proof, low-mintage and graded coins can be worth considerably more than their metal.
