Denier - Thierry II Saint-Dié

Thierry II ruled the Duchy of Lorraine during one of the most fractious periods of the Investiture Controversy, when the duchy itself became a recurring prize in the conflict between the Salian emperors and the reforming papacy. His right to strike coin at Saint-Dié derived from episcopal and comital privileges that were themselves contested during this period — the very existence of this issue reflects how local lordship over minting rights fragmented under imperial pressure.

Saint-Dié's mint output from this era is sparse in surviving examples, partly because the town's commercial role was limited relative to the major Lotharingian centers at Metz and Toul.
