COSTA RICA. Central American Republic. 1/4 Real, 1845-CR. San Jose Mint. NGC Unc Details--Surface Hairlines. KM-23. This already very popular and desirable pill-sized issue is quite <strong>RARE</strong> given the lack of a hole on this issue. Most of these were holed, so this intact specimen is sure to drive collector interest. A cleaning in the past has left evidence in the form of hairlines, but these are not destructive of any of the design elements. A hint of rainbow tone has formed on the peripheries where the sun rises on the design, creating a striking visual element.
