What is veinte pesos oro?

Answer 1

It is a coin made of gold. Some gold coins called "veinte pesos oro" (twenty gold pesos) were minted in Sudamerica during the end XIX century and the begining of XX century.

In Mexico there is one minted since 1917. At that time it was current currency, but today it is only a coin used for investment and it is valued according with its weight (it is almost half an ounce). Please check the official web page of Mexico Mint at:

where you can find the "veinte pesos oro" coin and also some other coins of "cincuenta pesos oro" (fifty gold pesos) and "diez pesos oro" (ten gold pesos). The whole family of coins is called "Centenario" (Centennial), because some of them were minted as conmemorative coins of the first centennial of Mexico independece from Spain (1810-1910)
