I just got this coin the other day. I love it, it seems flawless, and check out that mirror shine. This is the first UHR I've owned. Mintage on it is only 7500. Notice the sides of the coin? one is slimmer than the other? I am guessing that is due to the pressure from the coin being struck to achieve the UHR effect. That and the coin is 99.99% pure silver. The pics aren't the best, but the best I could do with the limited camera I have. Enjoy!
