Joao V gold 1600 Reis 1728-R VF Details (Damaged) NGC, Rio de Janeiro mint, KM126, Russo-183. Damaged at 2 o'clock near the rim, otherwise Very Fine for wear. A very rare type (the so-called "oval shield" Escudo) struck for only 4 years, with all dates of similar rarity and usually found in lower and/or damaged condition. Altogether missing from Eliasberg, while the 2 pieces in the famed Norweb group (1728-R and 1730-R) were damaged. A tooled VF hammered for $8,000 in 5/2013 in a US auction.
Estimate: 3000-4000 USD
