500 Pesos

Cuba's domestic security printing capability has always been constrained, and the Impresos de Seguridad facility in Havana has historically produced notes with a narrower range of security features than comparably denominated issues from other Latin American central banks. A watermark as the sole listed security feature on a 500-peso denomination is notable — at this face value, the absence of a security thread, color-shifting ink, or microprinting reflects either a deliberate choice or a production limitation.

The 500-peso note is the highest denomination in Cuban domestic circulation, introduced as the peso cubano economy operated in parallel with the now-defunct CUC convertible peso system. That dual-currency arrangement, maintained from 1994 until its formal unification in January 2021, gave the 500 CUP note an effectively marginal street value during much of the print run's lifespan.
