Ok, so I know that without reading it's not what people typically call a railroad rim but is that what is going on here? The rim pictures are 5aken from all the way around the coin so you can see 100% of the rim.
Since the retaining collar for the cent has a flat surface, I don't see how this could happen. Is it possible that the deformation was caused by a jewelry mount? I don't know. Chris
the reverse looks like some kind of bird. that said more than likely the rim was encased by a jewelry holder
Yep formerly an encased cent. When they make those they put the cent into a hole in the encasement planchet and then strike it with a die that has a hole in the center. Usually the hole in the die is slightly smaller than the diameter of the coin. It mashes the edge of the coin and causing it to "cup" and the metal of the encasement flows into the cup locking the two pieces together. If the design goes all the way to the edge of the hole you can end up with a coin that shows strange designs on the rims.
Oh yes it does look intentional! I agree, not a Railroad Rim but a former encased Cent like the majority of the members have stated
@Conder101 said it all. I also have one that is no longer encased if you'd like me to take some pics so you can compare. They do fool you at first making you think a possible collar clash but the cupped rim an is an immediate tell
A collar clash, by definition, can't cover the entire circumference of a coin. The radius of the collar is too large.
