Hey man I was doin a roll search on a box of dimes. I opened a roll and was looking at the edges and saw what appeared to be a silver edge and I thought I found a silver dime. When I pulled it out it looked silver but when I flipped it over from the reverse side to see the date there was no date because it was another reverse side? The coin has a reverse side on both sides? Have you ever seen or heard of this before?
