This 90% pure silver 5 Peso coin is part of a privately owned hoard of coins that never circulated, so it looks as sharp today as the day it came off the presses in Mexico over a half-century ago. Issued as a special railroad commemorative, it features a burly steam locomotive on the front, measures 1½" in diameter, and is a truly unique collectible that is as handsome as it is scarce. #0R06190
