Hemidrachm Aigeira

The Achaean League's federal coinage was one of the ancient world's more deliberate monetary unification projects — member poleis surrendered independent silver issues in favor of this shared federal type, with Aigeira contributing hemidrachms during the League's final, increasingly desperate decades. By 146 BC, Rome had grown openly hostile to the League's political consolidation, and the conflict that ended with Lucius Mummius sacking Corinth also effectively terminated federal coinage production across the Peloponnesos entirely.
