100 Pesos Guerrero - Gold and Silver Proof Issue

Part of Mexico's ongoing bimetallic commemorative program honoring the heroes of independence, this issue focuses on Vicente Guerrero — insurgent commander, abolitionist president, and the man for whom Mexico's southernmost state is named. Guerrero abolished slavery by presidential decree in 1829, a full thirty-four years before Lincoln's Emancipation Proclamation. He was executed by firing squad in 1831 after being betrayed by a political ally who lured him aboard a ship under the pretense of hospitality.

The .999 fineness of both metals is unusually pure for a bimetallic issue; most circulation bimetallics use standard alloys to reduce cost and improve durability in the press.
