It is strange using an ATM in Zimbabwe in that it dispenses US dollars. Unlike most US ATMs, it will dispense fifties and hundreds. Larger notes are mostly clean, but dollar bills are absolutely filthy. They are used until they fall apart.

Notes are US, but coins are South African rands.

Ecuador also uses the US dollar as currency, cash machines dispense $20s and $50s.

Tourists from the USA should bring $1 coins and leave $1 notes at home, people don't like the notes as they get dirty.

Ecuador mints coins (1, 5, 10, 25, 50¢) which are the same shape as US ones, and interchangeable in Ecuador.

Cambodia as well.

That would be nice, but with weight restrictions being what they are particularly on international flights, toting along an extra two pounds of $100 in coins is unlikely.
