The bishops of Basel held the right to strike coinage by imperial grant from the Salian emperors, a privilege tied directly to the city's position as a crossing point on the Rhine and a staging ground for trans-Alpine commerce. That economic geography, more than any ecclesiastical prestige, is why this mint operated continuously through a period when many episcopal mints across the Reich were losing ground to secular territorial lords.

Attribution within the 1072–1191 range remains imprecise; the series lacks the dated documentation that would allow tighter assignment to individual bishops.
