50 Colones Dice's cottontail, colorized

Costa Rica's cottontail coinage series reflects a broader push by the Banco Central to replace polymer notes in small denominations with longer-lasting bimetallic and treated coinage — a policy shift driven largely by the accelerated degradation of low-value paper currency in the country's humid tropical climate. The acrylic colorization process used here is applied post-striking, a technique increasingly adopted by Latin American mints seeking to incorporate wildlife imagery without sacrificing durability.

Dice's cottontail (Sylvilagus dicei) is endemic to the highlands of Costa Rica and western Panama, with a restricted range that has placed it under ongoing conservation scrutiny.
