Here goes the second thread. If you'd like more information on one of the pieces let me know and I'll be glad to get in a little deeper. This coin is known as the silver Centenario, it was minted in 1921 to commemorate the 100th anniversary of the independence of Mexico. This coin is quite older. it's a Ferdinand VII 8 reales piece. The Reales system was used during the colonial period (from 1521 to 1821). One peso equals 8 reales.
