25 Centavos Oswaldo Guayasamin

Ecuador has used the US dollar as its official currency since 2000, following a catastrophic banking collapse and currency crisis that wiped out savings across the country. These collector-issue centavo pieces carry no practical exchange function — they circulate symbolically, if at all, within a fully dollarized economy that has no use for fractional domestic coinage.

Guayasamín died in 1999, the year before dollarization, never seeing his face on an Ecuadorian coin.
