I got this odd ball quarter in my change today. First what caught my eye was that it’s not got the usual copper core visible on the reeds. I thought at first “great, one of those high school chemistry lab experiments again.” But then I noticed a few other odd things as well. Putting it next to another quarter, it’s just a hair thinner and slightly smaller in diameter compared to the other quarter. It also felt a hair lighter in weight compared to the other quarter. So when I got home I wieghed it against the other quarter I had. Sure enough, it does weigh a bit less. It doesn’t look like a dryer coin or too worn / damaged. Any ideas? First pic is of the weight of the quarter I’m comparing it to.
