8 Sestertius Ovidius

Not an ancient coin misattributed to paper — this is a modern commemorative banknote issued in 2018 honoring Publius Ovidius Naso, the Roman poet exiled by Augustus in 8 AD to Tomis on the Black Sea, a sentence he never escaped and whose cause remains genuinely disputed. The denomination "8 Sestertius" is a invented unit, a playful nod to the year of his banishment rather than any historical currency division.

Issued by a Romanian cultural or municipal authority — Tomis is modern-day Constanța — as a novelty or commemorative piece rather than legal tender. The watermark is a rare security concession for something with no transactional value.
