Ok guys I need some help. About 2 weeks ago I pulled what I thought was a 2006 silver proof Washington quarter. This has happened to me in the past and I assumed I had gotten lucky. When I opened the roll for my register the quarters non copper Reeded edge was glaring me in the face. So naturally I pulled it out and put it with my other silver proofs pulled from circulation. So today upon closer inspection, I realize that this quarter has a D mint mark. I thought silver proofs were issued through SFs mint. So what could explain a bright silver Reeded edge with no signs of copper and a D mint mark? any thoughts? also I can't do pictures from my phone so no back up evidence.
What explains it? A lot of companies, specifically the TV coin show people plating state quarters with gold silver and platinum and then selling them to people at inflated prices. Now that the state quaters have ended a lot of people have been trying to cash in on their investment in these plated coins only to find out they are only worth face value and a lot of them are getting dumped into circulation. This question about a "silver" quarter for a date and mint, especially of the state quarters, comes up a lot. The first thing you need to do is weigh the coin in grams, to two decimal places if possible. If the weight is 5.67 +/- .22 grams then it is almost certainly plated. If it is really silver it will weight close to 6.25 grams. If it weighs close to 5 grams and part of the reeding isn't there then it might be a quarter struck on a nickel planchet.
