Coin Museum

Run by the Treasury Department on Chakrabongse Road in Bangkok’s Rattanakosin district, the Coin Museum traces Thai currency from pod duang bullet coins to modern banknotes. The ground floor is free to browse; the main collection upstairs is guided-tour only, 50 THB per person, with tours departing roughly every 30 minutes and the last one leaving at 3 PM.

The bullet coins — solid silver rods bent into a loop and stamped with royal marks — are the centrepiece, and served as Thailand’s currency for centuries before flat coins took over. Beyond those, cases move chronologically through foreign trade coins that shaped the kingdom’s monetary system, coin-making tools and techniques, royal commemorative issues, and historic banknotes bearing past monarchs. Labelling runs in Thai, English, and Braille, and an English-language audio guide comes with the tour — a level of accessibility that’s rare among Bangkok’s smaller specialist museums.

Insider Tip: Go on a weekday morning right after opening — the guided-tour format means group sizes are naturally capped, but arriving early gets you the first slot and the quietest galleries before school groups and other visitors show up later in the day.

It’s a compact museum, closer to an hour’s visit than a half-day outing, and the tour format means you move through at the guide’s pace rather than wandering freely — a tradeoff that works well if you want context on the coins but less well if you prefer browsing at your own speed.

Watch out: Tickets and tour slots aren’t unlimited — turn up at least 10 minutes before a tour time to buy in and confirm your place, especially on weekends when opening hours shift to 10 AM-6 PM and visitor numbers rise.

The museum sits an easy taxi or tuk-tuk ride from Khao San Road and the Grand Palace area, making it a reasonable add-on to a Rattanakosin temple day rather than a standalone destination.

Pair it with the Bank of Thailand Museum for a deeper dive into the country’s monetary history, or Pipit Banglamphu Museum nearby for the neighbourhood’s own story.
