Moldovan leu banknotes were notable for not using intaglio printing until 2015: the main security features on all denominations were limited, initially consisting mainly of a watermark of Ștefan, a solid security thread, and a see-through registration device. In 2015, the National Bank of Moldova finally rolled out intaglio printing and embossing for denominations between 10 and 500 lei, and also introduced revised security features on all denominations except for 1,000 lei. The banknote for 1,000 lei, valued at €51.60 by currency exchange service XE.com on 31 December 2019, continues to use the original design.
