What cash currency should international travelers bring to Phu Quoc: newer US dollar notes, older notes, or Chinese yuan?

Chinese yuan are suggested as an alternative to US dollars. Check the actual local exchange rate, however: the discussion notes that US dollars had been the better-value option a year earlier.

For Phu Quoc, bring newer US dollar notes in crisp condition. Travelers report that even newer but crumpled bills may not be accepted everywhere and can receive a poorer rate; they advise avoiding older notes.

A contrasting traveler experience is that older US dollars bought at a favorable rate can sometimes work out better after double conversion. This does not remove the risk that a particular old or damaged note may be discounted or refused by an exchange desk.
