Unique Set of Mexico Proof Pattern Mint Errors

slab slab slab slab slab

This is a unique, incredible and dramatic set of 5 proof pattern mint errors. In 1990 the Mexico City Mint struck a new 100,000 Pesos Proof Pattern coin. It was struck in bronze with an extremely low mintage of 223, and is KM-Pn245. There are also a few known that were struck in brass, silver, aluminum and lead.

This set of 5 major mint errors is an exciting combination of rarity and spectacular eye appeal. Some of these are double struck off-center and in the collar, triple struck off-center and one is struck four times. They are all proof off-metals other than the bronze triple struck.
