Here’s something that you most likely you didn’t know about Romania:
Romania is the only country in the Northern Hemisphere that has plastic money and I don’t mean bank cards. The Romanian banknotes (bills) are made out of polymer (aka plastic). The first polymer banknote was introduced in Romania in 1999 with the occasion of the total Sun eclipse. Starting from the early 2000ds the National Bank of Romania gradually replaced the paper (which actually is cotton) bills with plastic ones.
Another thing that you might not know about the Romanian money is that there is no currency unit coin. The national currency of Romania is the Leu (which means lion) and there is no coin with the value of 1 Leu. Instead there is a banknote with that value.
