Here's a question for those coin buffs in our midst. I have this 1999P Test Quarter that is still sealed in its original plastic housing... Since I don't specialize in coins I decided to play around with a loupe I have, inorder to try to imagine what all those people that go to shows and sit at tables looking at coins through a loupes are trying to see.

While looking at the details of my coin through the loupe something comes off as odd...

Check out these pics. It looks like extra metal, bubbling or something weird is going on along the rim of the quarter. Would this be considered an error?


Thanks, Wiz

Very interesting. I have a 1999P 25ยข (in the test coin set) but it doesn't have any "bubbles" like yours anywhere on mine.

It appears that this could either be a defect in the plating process that commenced in 1999 or the result of a chip in the die that has the effect of creating areas of raised material on the surface of coins being struck. The latter could be confirmed by finding other coins with bumps of identical size in the same location. What makes this interesting is that it is in a sealed collector set. Although this speaks to quality control at the mint, I don't think it is uncommon and I wouldn't expect any premium to be paid for such a piece. You may however want to appeal to a PL set collector as some are particularly interested in anomolies such as this.
