Denier - Louis I Regensburg

Louis the Pious inherited an empire already minting under a reformed system — Charlemagne's 794 capitulary at Frankfurt had standardized the denier across royal mints, and Regensburg was among the workshops brought to heel under that order. Louis continued the reform coinage largely unchanged, which is precisely why attributing individual pieces to his reign rather than his father's depends almost entirely on subtle die and legend analysis rather than dramatic typological shifts.

Regensburg held particular strategic weight as a base for Carolingian campaigns into Bavaria and the eastern marches.
