For me it looks like J Ain M because the last letter is M. But the the other ones don't really look like J and Ain. Maybe you can take another picture?
I'm not orange and also in other things I'm not a Donald at all. DonChori like Don Felipe or Doña María, por favor.
I'm sorry, the second picture isn't better because its out of focus, too. But I'm still quite sure the last letter -on the left- is a "m" so you should have the second type (if on the other side of the coin there isn't any other inscription)...
