I had heard possibly that a private company may have gold-tinted a large batch of pennies in '74/'75, but have not come up with any results matching to my particular penny. It's stamped 1975 with a D mint mark, and I have pictures below showing the color difference of it between other pennies. If someone could tell me exactly what it is I have and the value that would be great! ___Front has some small scratches... ____ Reverse side has copper-like spots/stains. ____________ _____ Coin compared to a modern, and a pre-'82 penny to show coloration difference.
