0 Euro - Professioni Sanitarie

The 0 Euro souvenir program, administered through the Euro Souvenir Association and printed by Oberthur Fiduciaire in France, began in 2015 as a licensed novelty series. The notes conform to legal tender dimensions and security paper specifications closely enough to trigger vending machine validators — a known nuisance that prompted several European transit operators to update their sensor thresholds.

This 2021 Italian healthcare edition was issued during or immediately after the peak COVID-19 period, which gives it an obvious commemorative motive beyond generic souvenir tourism. Oberthur's production quality on these runs is consistent with their banknote work — UV-reactive fibers, intaglio-adjacent printing — which is precisely what makes the zero-denomination format legally permissible rather than counterfeit-adjacent.
