50 Euro Cents 2002 Germany (F & G) - Square v Rounded Edge

Just found these in a pile of mixed coins I bought back from Holland a few weeks back…

Not noticed this small variation before, and from the same mints too.  Anyone else found this?

I never looked for it, honestly…..

Interesting, isn't it?

Yes, very interesting.  The four coins I've found at the top of this thread are all German 2002G, so it also seems that it's not just different shapes for different years, or different shapes for individual mints.
