Watch List notes:

Potosi, Bolivia, piefort pattern 1/20 boliviano, 1865/4 FP, very rare, NGC MS 65. KM-PA3. 2.35 grams. Fully detailed strike with highly lustrous fields, totally devoid of wear or marks except on the relatively high rims, lightly toned, struck in almost double weight (as a 1/20 boliviano should weigh 1.25 grams) but not noted as such by NGC, only the second example we have seen.

Estimate: $700 - $1000
