The Onza is one of the more unique coins in the Mexican Mint’s long and varied history. First struck in 1949 and then again in 1978, 1979, and 1980, these coins are in some ways an homage to the mint itself. The standout image on these coins is the obverse coin press known as de balancín. This was the very first press used to mint coins in Mexico.

The Mexican Mint is considered the oldest minting institution in the Americas. Following a decree from the Spanish Crown, the mint was established in 1535 by Antonio de Mendoza, the first Viceroy of New Spain. The mint famously sat on top of Moctezuma’s Casa Denegrida, which was once an Aztec meditation house. That site is now a museum and the mint is currently located in San Luis Potosi in Central Mexico.

On the obverse side of 1 oz Silver Silver Onza Balance Scale Coins there is the image of a historic coin press. This type of press is known as de balancin and preceded steam and electric-powered minting devices. Along the edge of the field, there are inscriptions reading Casa de Moneda de Mexico. You will also find the year of release on the obverse field.

The reverse of 1 oz Silver Mexican Silver Onzas features a balance scale. Because of the historic theme of these coins, the scale is the vintage type with two bowls suspended at equal distances from a fulcrum. This might have been used at the mint to weigh and balance silver before it was struck. Inscriptions on the reverse read Una Onza Troy de Plata Pura Ley .925 Peso 33.625 Gramos. The Mexican mintmark can also be found on the reverse field.
