Watch List notes:

Cuba (struck at the Philadelphia mint), proof 40 centavos, 1916, NGC PF 61. KM-14.3. Bluish toning on lustrous fields with frosty details, minor marks all over, supposedly among only 50 struck but with a relatively high population of fourteen entries at NGC (several re-grades, no doubt), in any case popular with US collectors as a Philadelphia-mint product. NGC #4740171-003.

Estimate: $700-1000
