so Ive done some research around this site and haven't found much on my topic. I have a Penny where on the back it looks normal. But turn it to the front and there is nothing, its smooth Nothing filed off etc. To prove its smoothness I places on a flat surface and it laid flat. What would the value be on this? Ill have pics up once the film develops
Not only do we need pics but the weight would help. If the weigh is correct that will help us make a determination.
That's actually a pretty good indication that it has been altered. One sided coins ARE possible, but the blank side will not be completely flat.
