Abra was a small Iberian mint operating under Roman influence in the northeastern Hispania region, and its bronze coinage is among the least documented of the peninsula's autonomous civic issues. The chronological range assigned to this type spans the period of Rome's consolidating grip on Hispania following the Celtiberian Wars, when local mints were permitted — or perhaps quietly encouraged — to strike bronze for regional circulation while Rome controlled the silver.

ACIP 2278 is a rare attribution, with very few specimens recorded in major collections.
