These were printed between 1966 and 1990, though similar to the Soviet Ruble's 1961 series, they were only dated to 1966. Gold standard was abandoned after drastic measures were required to prevent inflation. This caused the Leu to lose exchange parity with other foreign currencies from 1970 to 1989. The exchange rate was set by the leadership through legislative measures. The exchange rate was used by the regime to calculate the value of trade to other states. These banknotes were prohibited from selling to private individuals. Possession or sale of currency was a criminal offense punishable by up to 10 years in prison. Foreign trade was considered part of a different economic circuit than the domestic one and was given greater importance. In 1987, hyperinflation began to appear and the National Bank wanted to issue higher denomination banknotes but Ceausescu refused. After the Romanian Revolution, these banknotes were kept in circulation even against the fact that all of them were coined in the first years. During the hyperinflation, these notes began to lose total value and after 1997, all socialist banknotes were completely withdrawn.

Following this, these banknotes continued to circulate with the later 1992-93 versions of these banknotes in parallel and were treated the same. Surprisingly, they lost more value than the socialist banknotes during their existence. 1992 Series Image Value Dimensions Main Colour Description Date of Obverse Reverse Obverse Reverse printing withdrawal 200 L 155 × 76 mm Light brown, blue Grigore Antipa Danube Delta December 1992 31 March 1999 500 L 160 × 76 mm Green, red Constantin Brâncuși Sculptures by Brâncuși 16 December 1999 1,000 L 167 × 75 mm Red, green Mihai Eminescu Putna Monastery May 1993 1 April 1999 5,000 L 172 × 77 mm Violet, blue Avram Iancu Densuș Church, Dacian Draco, Gate of Alba Iulia Citadel 180 × 77 mm Light red, violet Nicolae Iorga Șuțu Palace February 1994 16 December 2000 After the adoption of the new coat of arms with the Constitution of 1991, banknotes with the new coat of arms began to be printed. As a result of hyperinflation, not longer after the series was finished in May 1993, the new 10,000 Lei was introduced in 1994 (the first and only banknote with a segment thread that changes color (from purple to lime green)) as a result of the ongoing hyperinflation.

The 10,000 Lei received a colour changing strip, the first to be introduced in Romania.

A 500 lei coin and the 2,000 lei note shown above were made in order to celebrate the 1999 total solar eclipse. Whereas the 500 lei coin is currently very rare, becoming a prized collector's item, the 2,000 lei note was quite popular, being taken out of circulation in 2004 (a long time after the 1,000 and 5,000 lei bills were replaced by coins). The 2,000 Lei note became the first ever polymer note in Romania (and also in Europe) and was printed by Note Printing Australia in Melbourne.

Banknotes of the fourth leu (RON) The leu notes issued on 1 July 2005 are of equal size to euro banknotes, so that machines will need less refitting once Romania joins the euro zone. This decision was taken after a lot of debate, and with some opposition, the initial decision being to make them even smaller, similar to the 1966 series. The old leu notes were rather long and fairly uncomfortable to carry.
