Adalrich II served as Bishop of Basel from roughly 1025 to 1040, a period when Rhenish episcopal mints operated under direct imperial grant — in this case, a minting privilege confirmed under the Salian dynasty. Basel's position at the Rhine crossing made its mint commercially significant well beyond the diocese itself. The HMZ 1-190a attribution places this firmly within the early Swiss coinage corpus, though surviving examples are sparse enough that die studies remain inconclusive on precise emission sequences.
