Joao V gold 6400 Reis 1743-B MS61 NGC, Bahia mint, KM151, Russo-143. Attractive for the designation, with lustrous surfaces free of distracting contact marks. Gently wiped long ago and now attractively retoned. A scarce date, certainly very elusive in this technical designation. Only one coin is currently certified higher by NGC, and that example hammered for $23,000 as lot 23638 in our 9/2011 sale.
Estimate: 5000-7000 USD
