Joao Prince Regent gold 6400 Reis 1810/09-R MS62 NGC, Rio de Janeiro mint, KM236.1, cf. Russo-560 (unlisted overdate). Brilliant Mint State with essentially full mint luster and the few expected surface abrasions at this level. Some mild, non-distracting planchet adjustment marks seen on the obverse are mentioned for accuracy. A flashy and most attractive type coin, conditionally scarce in this quality.
Estimate: 1200-1800 USD
