Watch List notes:

Uruguay (struck in Montevideo), copper 40 centesimos, 1844, male sunface, wide convex planchet, medal alignment, rare, NGC XF 40 BN. KM-3. Rare variety struck on a strangely convex flan known as "bombe" (bulging on both sides) that commands a premium, yet with full details and less wear than the grade would indicate, also devoid of the usual crude nicks and marks, darkly toned against chocolate-brown surfaces. NGC #4216481-001.

Estimate: $4000-6000
