Republic aluminum-bronze Pattern 5 Piastres AH 1382 (1962) MS64 NGC, KM-Pn30. Only the second example of this very rare pattern that we have handled, the single other example we can reference being an MS63 from NGC, which achieved $1116 in our January 2017 weekly auction #231703 (lot 63243). Hardly a mark appears across the bright yellow fields, which for their part strike the viewer as very clean and nearly tone-free.
