I seem to recall that when the 2-euro coin first came out, it was the same size and weight as a 10 baht coin, so it had to be changed as the Thai coin was older and already been established. 

 

The two coins are very similar (note, the images are not to scale).

 

 

Sufficiently similar that when the Euro started in Belgium the office vending machines often had more 10 Baht coins than Euros. The source of so many Baht? - We made, amongst other things, coin validators. So there was a ready supply of foreign coinage, often just left lying around the lab. The company bought the 10 Baht coins back off the vending machine people for 2 Euros each, and implemented stricter control of the foreign currency.

 

Modern validators can tell them apart, but older machines may still acept to 10 Baht as a 2 Euro (or vice-versa).

 

 

Really, it is really rare coin.

Leave the coin outside next winter and then hit it with a hammer to see if the centre pops out.

I have a 10 baht paper note. A bit rarer.
