MEXICO. Peso, 1866-Pi. San Luis Potosi Mint. Maximilian. PCGS AU-53.
KM-388.2. Boldly struck devices boast a subtle iridescent sapphire sheen when their olive-gray color is illuminated. Still punctuated by some luster in the fields, this satisfying piece is an excellent relic of Maximilian's three year stint as emperor of Mexico.
Estimate: $300 - $400
