I found this 1988 D penny in my collection the other day when I was playing with my new microscope. I know there aren't supposed to be any documented doubled reverse or doubled obverse coins in this year/date. But take a look at this coin I think you'll find it to be very interesting as I did. It is doubled on the obverse and reverse. I would appreciate any questions or comments. Of Course I'd be interested in finding out if it's worth anything.
