Post a pic of the most beautiful 21st century coin.

But here's the catch.
1. It can only be a legal tender coin minted under the authority of a government.
2. It must have been issued for circulation by said government.
In short, I know there are plenty of beautiful coins issued for collectors, but what do you consider the most beautiful circulating coin?
