10 Colones Series A

Waterlow & Sons closed in 1961, which means the later dates in this series — if any notes were printed past that point — would have required a change of printer. In practice, Waterlow had already completed the print runs for this issue before the firm was absorbed by De La Rue, so the full A series was produced under a single contract.

The 10 Colones denomination sat at a meaningful middle tier during a period when Costa Rica's central bank, established only in 1950, was still building the institutional infrastructure to manage its own currency independently. Waterlow's engraved intaglio work on Latin American central bank issues of this period is consistently fine, though the Costa Rican notes from this contract are among the less-studied examples in regional collections.
