10 Euro Numex

Numex j.d.o.o. is a Croatian limited liability company, and this piece sits in the murky but legitimate category of privately issued fantasy or novelty currency — not legal tender anywhere, but produced as a collectible or promotional instrument. Croatia adopted the euro in January 2023, retiring the kuna after three decades, and the timing of this issue is almost certainly not coincidental.

Paper composition on privately issued pieces like this often varies significantly between print runs, and there is no central authority standardizing stock or production.
