25 Céntimos

Costa Rica's 1924 coinage was produced under contract at the Philadelphia Mint, a long-standing arrangement that reflected the country's lack of domestic minting capacity through much of the early twentieth century. The .650 silver standard adopted for this series was a deliberate reduction from finer earlier issues, driven by post-WWI silver price volatility that made higher-purity coins economically impractical for small-denomination circulation.
