8 Reales Type I Countermark

In 1841–42, Costa Rica lacked the infrastructure to mint its own silver coinage at scale, so the government authorized countermarking foreign eight-reales pieces — primarily Spanish colonial cobs and milled coins from Mexico, Peru, and Bolivia — to validate them as legal tender. The Type I punch, a small crude stamp, was applied by hand, making placement wildly inconsistent; the same host coin can appear with the mark anywhere from center field to the edge.

Host coin origin significantly affects collector interest. Bolivian macuquinas bearing the countermark are considerably scarcer than their Mexican milled counterparts.
