I found a 1999-P nickel with prominent doubling on P, 99, GOD, and also parts of the back, mostly in PLURIBUS UNUM. I wasn't looking for it and it was so prominent that it just popped out at me. I tried scanning it but the pics come out horrible, but has anyone found these things?
I also found a couple more with significantly less doubling, but it was there. Anyway I saved them, and I am still looking for them. My guess is they are not that rare.
