How the melt value is calculated
Melt value = gross weight × fineness ÷ 31.1035 × spot price. For the 50 centavos 1905–1918 (.800): 12.5 g × .800 = 10 g of pure silver. Divide by 31.1035 grams per troy ounce to get 0.3215 oz, then multiply by $57.35 spot: about $18.44.

Melt value vs collector value
Melt value is only what the silver in a Mexican Silver Centavos is worth at today's spot price. A coin's market value can be much higher: scarce dates, mint marks and high grades sell to collectors for a premium, while common dates in worn condition trade closer to melt. Nu Stack does not estimate collector prices on this page. For a specific coin, check the date and mint mark, the condition (a grading service such as PCGS or NGC, or a local dealer) and recent sales.
