100 Lei King Carol I

Romania's central bank has operated its own printing works since 1880, one of the older in-house facilities in the region, and this polymer issue comes from that same Bucharest operation. Polymer substrate adoption by the BNR has been gradual and selective — this 100 Lei is among the more recent additions to the series rather than a long-established format.

Pick 127 is current-issue and cataloguing data remains thin at this stage. The watermark listed as the primary security feature is notably minimal documentation for a contemporary polymer note, which typically carries a denser security package than substrate migration alone would require.
