BOLIVIA. 1/2 Sol, 1827-PTS JM. Potosi Mint. NGC MS-63.
KM-93.2. Variety with "CONSTITUC". Arresting coruscations of peripheral sapphire satisfactorily ring the warm amber-satin centers witnessed on this well produced minor. It is no surprise this piece is the single finest NGC has ever seen.
Estimate: $200 - $300
