Your photos are not clear enough to discern the markings on the coin. What I can see does looks promising on that one. If you are using a phone for pictures, try taking photo through your loupe.
That is better. You will have to experiment some. I think people with more knowledge than me pass over your post because your photo are not helpful. You are asking about smaller details on the coin that are hard to see. Can you tell which RPM this is?
#59 of 113? I don't know if my photo is a RPM or not, and it does matter if it is. The point is you can see the photo well enough to tell if it could be an RPM? And does your photo do the same thing?
What ever you have your enthusiasm always puts a grin on my face. I’m on your side. Good luck and happy CRH!
