Hi all, I am completely new to this site and infant to the world of coins. I just inherited a few coins from my grandfather, and after googling a few of them, one that I have shows some possible potential. I have an 1863 one penny coin, in my opinion its in a good condition (but what do I know!), has been kept in a little sleeve for many years. I've seen these selling on the London coin collection auctions for anything from a few hundred pounds to several thousands, and tbh I cannot really tell much of a difference between mine and the high sellers. I have read about the die numbers underneath the date, which I cannot see on mine, however I also can't see it on any of the ones that sold for the big bucks online. Could anyone shine a little light on this for me please? I have attached some pictures, best I could do with my phone sadly. Thanks, appreciate your time!
