Watch List notes:

Brazil (Rio mint), 6400 reis, Joao Prince Regent, 1808/7-R, encapsulated NGC UNC details / surface hairlines. Russo-unl. (cf. 558); KM-236.1. Unusually fine details and mirrorlike fields (prooflike) but with a few faint hairlines (not from cleaning), so probably some sort of special issue, very flashy and attractive in any case. Pedigreed to the New England Collection.

Estimate: $2000 - 3000
