0 Euro - Alpenzoo Innsbruck-Tirol

The Alpenzoo in Innsbruck holds a specific distinction: it sits at roughly 750 metres above sea level, making it the highest-altitude zoo in Europe, and specialises exclusively in alpine fauna — no lions, no elephants. The commemorative zero-euro souvenir note program, run through licensed distributors with Oberthur Fiduciaire handling production, has turned these into a minor collecting category of their own since the format launched around 2015. No legal tender status, no redemption obligation — the face value is purely nominal.

Oberthur's inclusion of a genuine security thread and colour-shifting ink on a note worth nothing monetarily reflects how the program sells the format itself as the product.
