Denier Bracteate - Diethelm of Krenkingen and Werner of Staufen

Historical Context: This Denier Bracteate from the Bishopric of Constance, 1190-1209, is a crucial numismatic artifact from a politically turbulent era. Issued during Bishop Diethelm of Krenkingen's tenure (1189-1208), its joint attribution with Werner of Staufen, an anti-bishop (1206-1208), highlights a complex power struggle within this significant prince-bishopric. The coin likely represents a period of uneasy co-existence or temporary resolution, reflecting the intense rivalries and fragmented authority characteristic of the High Middle Ages.

Artistry: This silver denier, a typical bracteate, is uniface, struck from a single die onto a thin, often irregular flan, characteristic of Germanic minting. While the precise design is not detailed, Constance bracteates commonly featured stylized depictions of the bishop, like a mitred bust, crozier, or architectural elements. Given the dual attribution, the design likely incorporated symbols representing both Diethelm and Werner, or a generalized ecclesiastical motif, prioritizing bold, immediate recognition over intricate detail.

Technical/Grading: Weighing a mere 0.44 grams, this silver bracteate exemplifies its type's inherent fragility and thinness. Key high-points, such as a mitre's apex or prominent facial features, are prone to weakness or wear due to the single-die strike and malleable metal. A well-preserved example exhibits a clear, full strike with minimal flan buckling or creasing, and a strong central design impression. Centering is often irregular; sharp details in legends or smaller elements are highly prized, given striking challenges.
