Thai coins actual type

I have these two Thai 10 baht coins



Can someone tell me please, which of these two types are my coins (I assume they are the same type).

Can't see a difference

Thanks in advance

  The one on the left is the small portrait. Admittedly there is only a slight difference, and only noticeable when coins are side-by-side like yours. Top of the head is closer to the border in the large portrait.
