What country's currency is Ron? What's the exchange rate with the US dollar?

RON is not short for money. Like RMB, it is the international code of Romania's leu.

Romania started from 1880. Although the name of the currency has not changed after many currency changes, Leu is singular, LEI is plural, and all China people are called Lei! Leu and Lei are actually different old and new coins on the first floor, which is really a big joke. The parity of the old and new coins is correctly written as 1Leu= 10000Lei.

Just look at the picture. The old money is on the left and the new money is on the right. Romania's last release of 1 lei was version 66, and the subsequent 10000 lei was version 98. Later, during the reform, it was changed to the current 1 lei.
