COSTA RICA. Central American Republic. 1/2 Real, 1848-CR JB. San Jose Mint. PCGS AU-53.
KM-20A. "CREZCA" spelling variety. A boldly struck silver minor with fields that retain flashy, lustrous properties despite some gentle wear across more exposed areas. This the type without counterstamp, and is actually scarcer than the type with counterstamp.
Estimate: $150 - $250
