Been visiting Thailand for over two decades but was told something I’ve never heard, before and am unsure if it is true.
A very well educated Thai friend said “If taking cash, try to take high denomination notes” (£50 notes in my case but would be $100 bills for others).
They explained that money exchanges in LOS pay a higher exchange rate for higher denomination notes than otherwise.
I said they were disseminating Fake-News but other Thais waded in and said it is true and that even the currency exchange-rate boards hanging up in the booths show the higher rate differentials for larger notes.
I’ve never been aware of this phenomenon nor noticed that.
Have I been walking around with one eye closed?
TLDR : Answer Summary
Many expats and travelers in Thailand confirm that exchanging cash with higher denomination notes, such as $100 or £50 bills, often results in better exchange rates compared to lower denominations. This practice appears to be a widely recognized standard at various exchange booths across Thailand, with some users suggesting that perfectly crisp and newer notes earn even better rates. Several comments indicate that values can vary depending on the exchange company and the specific currency, but the consensus seems to support the idea that larger notes generally provide a more favorable exchange rate.
