What Euro banknote denominations are easily accepted in Thailand for exchange?

In Thailand, most Euro banknotes are accepted for exchange, with the 50 Euro and 100 Euro notes being the most common. Larger denominations, such as the 200 Euro and 500 Euro notes, can also be exchanged, but they may face more scrutiny and need to be in excellent condition. While Euro notes in good condition are preferred, it's noted that 500 Euro notes are no longer officially issued, and 200 Euro notes may be less commonly accepted but generally can be exchanged if they are clean and unmarked.
