Maria I gold 6400 Reis 1788-R (West Indies Imitation) MS61 PCGS, Imitating Rio de Janeiro mint, Cf. KM218.1 (for prototype). A highly interesting and pleasing example of this scarce series of imitations, struck at a somewhat lower weight (12.5 g) than the regular issues. Incredibly lustrous, with a minimal number of scattered hairlines. Worthy of much consideration.
