0 Euro - Frombork - Nicolaus Copernicus Museum

Frombork — the small Warmian town on the Vistula Lagoon where Copernicus spent the last three decades of his life and completed De revolutionibus — is home to a museum occupying the cathedral chapter complex where he worked and died in 1543. The EuroSouvenir program, launched in 2013 and officially sanctioned by the European Central Bank under strict conditions prohibiting legal tender status, has become the primary vehicle for this kind of regional cultural commemorative. Oberthur Fiduciaire, long one of Europe's serious security printers, brings genuine banknote infrastructure to what is ultimately a collector souvenir — security thread and watermark included, which is a requirement of the ECB licensing agreement rather than an aesthetic choice.
