Republic gold 10000 Reis 1889 MS64 NGC, Rio de Janeiro mint, KM496, Russo-688. Choice Mint State with attractive and delicate patination over lustrous surfaces and very light scuffing marks likely preventing a higher technical designation. An uncommon type, very rare and desirable in this lofty quality, the present example currently tied with another coin as the finest graded of the date by NGC, with only one other graded finer for the entire type.
Estimate: 3000-4000 USD
