1 Dinar Otto von Guericke

Prometheus Island has no recognized sovereign existence, and the "Prometheus Island National Bank" is not a licensed monetary authority under any jurisdiction this catalog has been able to verify. This is almost certainly a fantasy or novelty note — produced to be collected, not circulated. The Otto von Guericke attribution in the denomination name is an unusual choice for a fictitious issuer, referencing the seventeenth-century German physicist and mayor of Magdeburg best known for his vacuum pump experiments and the Magdeburg hemispheres demonstration of 1654.

Polymer substrate and hologram inclusion on a fantasy piece suggest a print run aimed squarely at the collector market rather than casual novelty production.
