MEXICO. Peso, 1866-Pi. San Luis Potosi Mint. Maximilian I. NGC Unc Details--Cleaned.
KM-388.2. From the challenging San Luis Potosi emittance, bright steely surfaces show some localized pewter gray overtone on the obverse which becomes more dominant on the reverse. While there is some unnatural friction in the fields, detail is consistent with the Mint State grade level and should entice strong bids.
Estimate: $400 - $600
