Silver dime looks from the front almost as if the edges are cut or engraved . . . but the back is even stranger. The edge is not ground down at all - this coin doesn't have a smaller circumference than a normal dime.
I'm excited with my find. I did the best I could with my phone to take this picture. The edge at 11 o'clock looks like a number 5! Is this concierge a MPD? I'm sorry about having to post this on someone else's thread. I couldn't figure out how I did it before.
Just damage... The only way a number from the date could be on the rim is from a "dropped letter" error. That's where gunk fills the letter or number and compacts then falls out and is struck into the coin which can happen on the edge too. But with a reeded edge I'm not sure it would even show and it definitely would not deform the metal.
