Melt value is what the pure gold or silver in a coin is worth at the spot price.
- Fine weight = gross weight (g) × fineness (‰ / 1000).
- Value = fine weight (g) × spot price per gram.
- 1 troy ounce = 31.1034768 g; price per gram = price per ounce ÷ 31.1034768.
Spot now: gold …/g, silver …/g, platinum …/g.
When the statute declares fine content
Some laws state fine content directly. U.S. law says the $50 American Gold Eagle «contains one troy ounce of fine gold». We then use 1 troy ounce of fine gold. The London Gazette Britannia silver proclamation states 32.454 g at 958.4‰ with «ONE OUNCE FINE SILVER».
