Denier - Lüthold von Aarburg

Lüthold von Aarburg served as Bishop of Basel from 1191 until his death in 1213, a period when episcopal mints in the Upper Rhine region were under persistent pressure from competing secular lords. The Bishopric of Basel held minting rights as a imperial fief, a privilege confirmed and contested repeatedly through the Investiture Controversy's long political aftermath. At 0.36 g, this denier sits at the lighter end of the regional bracteat-adjacent coinage, reflecting the progressive weight reduction common to Swiss episcopal issues of the late 12th century.
