Hello, I received this dime with some change. It is quite thinner than a regular dime, the octagonal shape has me really confused (like a Canadian dollar?)
, especially since it's only really prominent on the obverse. In the center, it seems normal-dime-thickness, it's raised on both sides at that point. There is no prominent rim, & there is varying thickness along the edge. It's incredibly smooth.
Did someone just sand & polish this guy down? I'm aware that this dime isn't worth not much more than down payment at a vending machine, because the date is not visible (if it were a manufacturing error). However, I'd love to hear any thoughts!
