João V gold 12800 Reis 1730-B MS62 NGC, Bahia mint, KM141, Russo-101. 2nd shield type. Lustrous Mint State with strong subjacent luster under handsome old patination and only the scattered mild surface handling marks expected at this level. Rare in any grade - as any gold Dobra struck at Bahia - and most desirable in this outstanding condition, a superb example that sits atop the current NGC census of this coveted issue and must be among the very finest extant: it appears vastly superior to the RLM (AU50 NGC), Eliasberg (AU53 NGC) and Norweb ("Cleaned Very Fine") examples.
Estimate: 30000-40000 USD
