Pedro II gold 10000 Reis 1845, KM457, Russo-626, MS62 NGC. Mintage: 3,834. Almost entirely free of individually identifiable marks with bright luster and a pleasing strike. A semi-key date for the series, and a conditional rarity this nice with inspection of the NGC and PCGS censuses showing the present coin as the finest certified and the only example to reach the Mint State tier.
Estimate: 4000-6000 USD
