I went into a pawn shop who I have done business with in the past but never in the capacity of collecting coins. Anyways on my way to get some lunch on Wednesday I decided to stop by there and I saw a $2.50 (quarter eagle) gold piece and it was in a bezel. I looked at it and I asked to see a loupe which the man gave me. It was dated a 1914 if memory serves me correctly. Upon further inspection I saw what looked like copper painting like spray paint. I asked him if it was tested and weighed and he said that it was. Now normally I would forget about it but I've never heard of gold toning and that was his answer to the color change. Oh, there was something else that I noticed as well On the E Pluribus Unum, the “E” had an error on it. The top line of the E was not straight across, wish I had a pic but I don't. Personally I've never seen a gold piece or ring or anything to do with gold ever tone. Excuse the question, am I wrong? Do gold coins actually tone? The price was marked way too high at $325 but I think I will go back there and actually speak to the owner this time.
