10 Lei COA with crown

Romania has issued its 10 Lei note continuously on polymer since 2005, and the P#119 series has accumulated suffix letters steadily through incremental security upgrades rather than full redesigns — by the time the "j" suffix was reached, the changes between iterations were largely invisible to casual handling. The platform itself was pioneered by Note Printing Australia, which produced the earliest issues; later production runs have involved additional contractors as the series matured.

Polymer 10 Lei notes from the 2018–2024 window circulate heavily and show wear faster along the vertical fold lines than paper equivalents would.
