Hey, we've got Monopoly money now!
We had the same opinion about the new Euro, you know. Our old Deutschmark bills were colored, but in mild pastel tones. Now some painting shop dumped all their brightest colors on the Euro! 🙂
The best argument for exchanging the old bill for new ones is: all the dirty (forged and originating from robberies) money will have to turn up or become worthless. Now all the cheaters and forgers have to start anew, even if they own the printing blocks for the old dollars. That's difficult and expensive.
They say our new Euro is almost impossible to forge, but I don't believe that. It sure can't be color-xeroxed because of the relief imprints. But where there's a criminal mind, there's a way...
Our old Deutschmark bills had Braille script for the blind. They forgot it on the new Euro! Too costly, I guess...😡
