Penning - Burkhard

Burkhard van Weiflingen held the See of Utrecht from 1099 until his death in 1112, a tenure defined largely by the Investiture Controversy still convulsing the Empire. His episcopate fell in the immediate aftermath of the Concordat negotiations that would eventually produce the Worms settlement of 1122, and Utrecht's mint activity under him reflects the broader instability of episcopal authority during that period — bishops caught between papal reform demands and imperial patronage on which their temporal power depended.

The van der Chijs reference places this type among the scarcest of the Utrecht penning series.
