#20 (pyota)

As for CHF 1000 notes being in "common use", I concede that they are only common if they are appropriate, which is not that often (it's over 900 USD, after all). They are useful, for instance, to those who pay for their cars in cash (there are quite a few of them).

People are used to larger notes in Switzerland; ATMs dispense 100 CHF notes by default. A few years back, I purchased a train ticket (some 20 CHF or so) using a 1000 CHF note, and the salesperson didn't even raise an eyebrow.

The 500 Euro note is certainly not (yet?) the most valuable note in the world. The Swiss 1000 CHF note is currently worth 620 Euros. It is in common use, too, although hardly in cafes.
