$2 bills are awesome, have a small stack(get one for every birthday). Used one once, and the girl behind the counter said, ‘We don’t accept monopoly money’.
I love $2 bills. I’d always get some when I cashed the paycheck back in the States.
Here, the smallest bill is 100 Kc (Czech crowns) - goes all the way up to 5,000 Kc. That’s roughly from a $5 to a $250 bill at rate of exchange. 1,000’s and 2,000’s are common enough here. Anything below 100 Kc is a coin.
