Joao V gold 4000 Reis 1712-R MS63 NGC, Rio de Janeiro mint, KM102, Russo-164. Choice Mint State with strong mint bloom and remarkably clean surfaces for the designation. A tad scarcer date and a lovely type representative, rare and most desirable in this lofty preservation. Currently the single certified example of the date by NGC.
Estimate: 3000-4000 USD
