I have found this odd looking 1961D lincoln penny. if you look close it has little cuts/notches 'whatever' all around both the front and back -right out on the edges. so I weigh it and it seems light..? ( 3.012 grams ) Is this anything worth investigating????
Not worth investigating. Someone purposefully damaged the coin for an unknown reason. The weight is a little low but within tolerances I think. Worth 1 cent.
Post mint damage. People do many things to coins when bored. Vice jobs, spooning, coca cola baths, Mercury dipping.
