Joao V gold 12800 Reis 1731-M AU58 NGC, Vila Rica mint, KM139, Russo-287. A lustrous coin, with only scant friction evidence preventing the Mint State technical designation and substantial subdued mint luster. As sometimes seen, the obverse surface is slightly porous, the result of a striking from a rusty die. A popular large gold issue, very scarce and much in demand in this engaging preservation.
Estimate: 6000-8000 USD
