Æ19 - Trebonianus Gallus ΑΡΓΩ ΜΑΓΝΗΤΩΝ (anti-clockwise and retrograde)

The Magnetes of Thessaly were among the more obscure civic minting authorities still operating under Roman imperial oversight in the mid-third century, issuing small bronzes that circulated locally long after most provincial mints had gone quiet. The retrograde, anti-clockwise legend on this piece is not a die-cutter's error — it appears consistently across the type and may reflect a deliberate workshop convention, possibly the hand of a single engraver whose training was irregular or whose model was a reversed impression.

Trebonianus Gallus reigned barely two years before being murdered by his own troops in favor of Aemilianus.
