Maria I gold 6400 Reis 1792-R MS63 NGC, Rio de Janeiro mint, KM226.1, Russo-530. A flashy specimen with considerable mint bloom and the few handling marks expected for the designation. Struck from a deteriorating obverse die with various die breaks visible to the naked eye on the peripheries. Undoubtedly scarce and quite desirable in this fine quality.
Estimate: 1800-2200 USD
