I like the variety. Not all of them resonate with my artistic values, but I do appreciate them on their own terms. I think that these point to the future of circulating coinage.
Consider this: America's classic coins, the Walking Liberty, the Buffalo Nickel, and of course the Saint Gaudens $20, were created by artists who used coining as another medium for expression. The reason that previous American coins were lackluster is that the Mint hired "coiners." That was fine. It met a practical need. However, the stunning coins came from thinking outside the box.
Has anyone here seen recent example of medals? They are not "coins" any more!

These are the outer limits of "coin" art. Coins will not look like all of these things, but these things influence what coins become.
Casino chips are electronic devices. That is another trend.
I like these new coins. I think they are innovative, creative, thoughtful and thought provoking.
