COSTA RICA. Colon, 1923. San Jose Mint. PCGS MS-61.
KM-164. A countermark, grading UNC Detail, placed upon a 1903 Costa Rica 50 Centimos. The host is relatively free of toning, with frosty luster in the fields. The Countermark has been so boldly stamped as to completely erase any of the host design underneath.
Estimate: $100 - $150
