My first commemorative coin

I paid for 2 amazing pastries with 20€ bill, and the handsome salesman apologized, 'cause had to give all the change in coins...

(ta-ta-ta-daa <- drum roll)
my first commemorative 2€ coin also!
It is a German 2010 coin, Fifth of the Bundesländer series, depicting City Hall and Roland (Bremen)...
