0 Euro - Bilíkova chata

Bilíkova chata is a mountain hut in the High Tatras, Slovakia, sitting at roughly 1,255 metres above sea level and dating to the early twentieth century — one of the older overnight shelters on the trail network below Slavkovský štít. The zero-euro souvenir format was introduced by EuroSouvenir around 2015 and relies entirely on Oberthur Fiduciaire's security printing infrastructure to lend the pieces credibility: genuine banknote paper, intaglio printing, and a valid EURion constellation, which means automated cash-handling equipment will actually detect them as currency-adjacent objects.

Legal tender for nothing, but produced to the same technical specification as circulating euro notes from participating central banks.
