gotboostedvr6 Valued Member United States 261 Posts	Posted 02/07/2014 09:45 am I'm hoping that some members on here might be able to help me with this. I'm wondering what the actual composition is of Mexican coins from the 40's into the 60's. I'm not just looking for the precious metal content but the base metal content too. Thanks guys Report this Post to the Staff

Libertad Pillar of the Community Canada 3692 Posts	Posted 02/07/2014 09:58 am Two options for accurate results: -Contact La Casa de Moneda de Mexico (Mexico City Mint) and email them a question. They try to maintain an image of transparency, so this type of question shouldn't be out of line. -Bring some coins into a refinery for an assay. For a fee they will tell you the exact compositions. My amateur guess is that there some copper along with a tinge of zinc (some .720 fine silver coins turn yellow after circulating). Report this Post to the Staff
gotboostedvr6 Valued Member United States 261 Posts	Posted 02/07/2014 1:03 pm I sent a email to the mint. . Crossing fingers I'm particulary interested in the 1964 peso. Report this Post to the Staff

They are dipped in a bath of pure silver before striking to improve appearance. Source: "A Guide Book of Mexican Coins, 1822 to date," by T. V. Buttrey and Clyde Hubbard Report this Post to the Staff

gotboostedvr6 Valued Member United States 261 Posts	Posted 02/14/2014 10:12 am Nothing yet from the mint. A friend of mine that is a Mexican citizen is rewording my email in Spanish to resend to them. Report this Post to the Staff
Libertad Pillar of the Community Canada 3692 Posts	Posted 02/14/2014 11:45 am I just worked the metal on this peso. That metal is TOUGH, wow, it's about as bad as nickel white gold (15-20% nickel) maybe harder. I'm surprised it doesn't have a higher nickel composition than just 100/1000 parts. In future, if you need a translation I may be of help. Report this Post to the Staff
