A local coin shop can make an offer. Melt is the metal floor, not a quote. Many shops buy generic gold and silver as a percent of that number.
What this coin is
Pre-1905 Mexico 20 pesos gold, 87.5% fine, 33.84 g, 0.9519 oz AGW — nearly a full ounce, and about double the later VEINTE PESOS Azteca (16.67 g, 0.4823 oz).
What is written on the coin
VEINTE PESOS on the old type, not the Aztec calendar stone of 1917–on. Calendar stone = .900 Azteca on the other page.
Metal content (the melt spec)
Mint specification: 33.8400 grams at 87.5% fine, which is 0.95190 troy oz of pure gold (AGW). Formula: grams × fineness ÷ 31.1034768. Date and mintmark do not change that number. Melt today is $4,190.26 per coin at $4,402.00 gold.
Mintage
1870–1905. Much less common in junk gold lots than Azteca restrikes.
A little history
Heavy .875 veinte before the 1905 reform. The Azteca calendar 20 pesos is the later, lighter .900 coin people usually mean by “veinte.”
How to tell you have this type
No sun stone + ~34 g = this page. Sun stone + ~16.7 g = Azteca VEINTE PESOS.
Date and mintmark do not change the metal on this page. Collector value is a different market — see Sold Comps for sold prices.
