1 Centavo

Cuba's aluminium centavo series persisted well into the 21st century largely because the dual-currency system introduced in 1994 — the CUP for locals, the CUC for tourists — made low-denomination coins effectively irrelevant to hard-currency transactions. The centavo soldiered on in domestic circulation anyway, used for state-subsidized goods and fares that hadn't seen a real price adjustment in decades.

The series was rendered obsolete when Cuba announced the elimination of the CUC in 2020-2021, collapsing the two-tier system that had defined Cuban monetary life for nearly thirty years.
