6 Kreuzers - William IV and Louis X

William IV and Louis X ruled Bavaria jointly from 1516 under a co-regency arrangement forced on them by their father Albrecht IV's partition wishes, though the brothers spent much of that period in genuine political tension. The 1536 date places this coin just two years before Louis X's death, which finally ended the awkward dual administration and left William sole ruler of a consolidated duchy.

Joint-reign coinage from this period is structurally uncommon — administrative friction between the two courts complicated mint output.
