Joao V gold 4000 Reis 1715-B MS62 NGC, Bahia mint, KM106, Russo-61. Brilliant Uncirculated with substantial underlying luster and remarkably clean surfaces for the assigned grade. A quite exceptional example of this very rare date, missing altogether from the Norweb, Eliasberg and, more significantly, RLM collections. It is also the single example of this rarity previously handled by us and currently the single certified specimen by NGC.Ex. Heritage (Heritage Auctions 8/2010, lot 20273 for $4,750)
Estimate: 5000-7000 USD
