I'm going through some Thailand 50 Satang coins and have noticed that there are two different types of coins. One appears to be more red and magnetic while the other appears more green I think (I'm partially color blind) and not magnetic.
I found 2 coins, both dated BE 2551 (2008 AD) of each type. There are several differences in the two 50 Satang coins as far as detail go, font styles, etc.
Since I have several coins that are magnetic and several that are not (all 50 Satang) I'm wondering if there's more than 1 mint making them? Any ideas?
