Watch List notes:

Uruguay, copper 5 centesimos, 1840, heavy flan (extremely rare), NGC XF 40 BN. KM-1. 6.48 grams. Full details with only light wear but somewhat rough surfaces (as made), a rare type in general but this specimen the extremely rare subtype on heavy planchet corresponding to the original decree of 1839, characterized by a single pair of dies and thus correctly catalogued as a different subtype by Almeida. The stricter, heavy-weight standard and single pair of dies points to a limited run of early trial pieces. NGC #4234309-001.

Estimate: $3000-4500
