What made you annoyed today?

I wonder how much 100 EUR banknotes are generally in circulation, not just because the cashless payment from our everyday life is indispensable. In addition, the notes at the cash register are no longer checked for authenticity! Only when counting, according to a seller. So something is not "kosher" here.

I wonder how much 100 EUR banknotes are generally in circulation

Well I can answer that, at least how many it were in 2019:

Derzeit befinden sich rund 22,1 Milliarden Euro-Scheine im Umlauf. Davon sind rund 2,8 Milliarden Stück 100 Euro-Banknoten, was einen Anteil von etwa 12,8 Prozent der im Umlauf befindlichen Stücke ausmacht.

Der 100 Euro-Schein ist – nach dem 50 Euro-Schein – die zweitwichtigste Banknote im gesamten Euroraum. In Deutschland ist hingegen der 20 Euro-Schein von größerer Bedeutung.
