USA Administration Peso 1906-S AU Details (Surface Hairlines) NGC, San Francisco mint, KM168. The key date within the business strike series of Pesos, with most of the original mintage being melted down. Some scattered marks and hairlines, but an overall highly pleasing example of this rare date, with a great deal of detail remaining along with very little evidence of circulation.
Estimate: 2500-3500 USD
