20 Sestertius Marcus Aurelius

This is a modern fantasy or novelty piece — no Roman emperor ever issued paper currency, and the sestertius was a bronze and later orichalcum coin. Rome had no paper monetary system. Items like this are typically produced as educational aids, souvenir collectibles, or outright fakes dressed as historical curiosities, and they carry no numismatic value in the conventional sense.

The watermark is a modern security feature entirely anachronistic to the supposed period. Worth cataloging only as a 21st-century novelty, not as a historical document of any kind.
