Æ22 - Tiberius L CASTRICIO REGVLO IIVIR QVINQ COR

Corinth's colonial coinage under Tiberius was administered through locally appointed duoviri quinquennales — magistrates elected every five years to oversee the census and civic finances, a rank considerably above the ordinary annual duoviri. L. Castricius Regulus held this office and placed his name on the coinage accordingly. The Julio-Claudian colonial mints in Achaea operated with considerable autonomy in naming magistrates on bronze issues, a practice Rome tolerated as long as the imperial portrait remained prominent.
