I have a 1981 nickel that I can not tell if it is a P or D because it is a circle or smudged. I wanted to see if it is an error. http://imageshack.us/photo/my-images/7/nickel1.jpg/ http://imageshack.us/photo/my-images/716/nickel2.jpg/ If it is an error, how would you determine the value of this nickel?
It looks like a filled "D". This is caused by a die chip. The small post that would create the center of the "D" has broken off and the metal filled the void. No added premium for this.
