The Mexico City Mint is the oldest in the New World. Established in 1535, it has produced untold numbers of coins. And every year since 1982, a 1 ounce Bullion Silver coin, the 'Libertad' has been minted. It's always one of our best sellers, and they always sell out quickly at the Mexican Mint. NOTE: Prices are subject to rapid change due to fluctuations in silver!
