I found this 2000 Lincoln cent and yes it does have some zinc rot on the edge, but that is not what is causing the weight to be so far off. The coin weighs 2.29 so I am thinking it's a dime. If you look, you can slightly make out an image of Roosevelt. (or where he is supposed to be on the coin) You can also see some lettering that is not on a lincoln cent. If you look close at the edge, the coin is very thin just like a dime.And you can also see where the coin had a reeded edge. What do you all think? And if I am correct.... would there still be value in the coin considering the condition?
