Thank you Chrisild and Numismat for identifying the 10 Peso pill (coin center) that I posted yesterday. I've taken new photos, as the lighting was poor on the first set of photos. I've also cleaned and polished the piece. Here you can see the actual silver color. I'm assuming that it may be .925 (is this true for the 10 Peso coin?). Anyway, thanks to you guys, I learned something about Mexican Pesos.
It doesn't particularly look like silver. The metal is not as bright. PS: It wasn't necessary to start a second thread, please just add it to the already existing one next time. =)
