Melt value vs collector value
The Mexican Gold Libertad is a bullion coin, so its price tracks the gold spot price. Buyers and sellers usually quote it as a premium over (or a discount to) melt value, and that premium depends on the dealer, the year and the coin's condition. Special and proof versions can sell for more. Melt value is the number to anchor on: it's what the metal alone is worth today.
