0 Euro - Bojnice Castle

Euro Souvenir notes occupy a peculiar commercial niche — legal novelties printed to full ECB-specification security standards, including genuine Oberthur watermarking and holographic strip, yet assigned zero monetary value by design. Oberthur's involvement is not incidental; the program's credibility depends entirely on using the same contractor infrastructure as legitimate euro production.

Bojnice Castle, one of Slovakia's most-visited tourist sites and a 19th-century neo-Gothic reconstruction of a medieval core, is a predictable subject for the series. The Slovak souvenir note program launched in earnest around 2018–2019, tracking similar initiatives already running in France and Germany.
