Ta, I will be after those!

I now have one each of the new polymer 50 and 100 Baht banknotes that were first issued on 21st November 2025.  Will Numista be adding them to the catalogue so that we may add them to our own collections? 

If you have them you can add them yourself. Numista is made by the community for the community.

Its a good idea, as the 50 and 100 Baht are widely used in markets and the like. There is also a gap between the 100 and 500 baht, which means usually multiple 100s are used. 100 baht is worth around $3 USD and 500 - $15 US, so hence their importance, especially amongst poorer and more rural Thai. Also consider Thailand even in its cities has many roadside stalls, tuk tuks and baht buses that rely on large amounts of low value notes and coins.
