YUROP

The Euro notes look like what you'd get if you asked for prop banknotes for a minor scwne in a nwar-future sci-fi movie. The basic design elements are there to give the general look of currency, but something always seemed missing.

I think it's the lack of text-- most banknotes have a big, prominent issuing authority name rather than the tiny copyright line of abbreviations, and often some flowery "I promise to pay on demand" legal language leftover from when the note was a stand-in for a stack of silver coins.
