On 25-Nov-2015, the new €20 Euro banknote (Europe Series) entered circulation in the Euro Zone. Today, I got my first one in change.
The serial number (more precisely, the first letter of it: R ) shows it was printed at Bundesdruckerei in Berlin. There are reports at German coin forums that €20 notes printed at Giesecke & Devrient in Leipzig (W) and Munich (X) have also been found. The factory in Munich has been closed a couple of months ago. So, no more new 10s and 20s with the prefix ''X'' in the future.
Sorry about the double post.
