Not sure what to make of this. I thought I found a silver state quarter when rolling my pocket change but it has a "D" mint mark instead of an "S". The edge is solid silver but I really can't tell a difference in the weight. I tried a balancing stick with a known zinc quarter on one side it it seems to be almost identical in weight. It also seems to sound similar which makes me think this is either a counterfeit or some sort of error. Has anyone seen this before?
Thanks for the reply! I suppose there are a multitude of reasons someone would do this and none of them good. Just wanted to make sure I wasn't missing anything. Cheers
Likely some science experiment done in a school. I remember some electroplating experiments back in the day in high school.
Doesn't even have to be a science experiment, how many ads have you seen for Gold, Silver or Platinum coated State Quarters...get yours now...
