24 Kreuzer - John Casimir and John Ernest II

This issue falls squarely within the Kipper und Wipperzeit — the catastrophic currency debasement crisis that swept the Holy Roman Empire beginning around 1619, driven by opportunistic mints racing to produce overvalued small silver coins before their trading partners caught on. Saxe-Coburg-Eisenach was among dozens of minor German states that exploited the chaos, striking debased multiples far in excess of their actual silver content. The 24 Kreuzer denomination was a workhorse of this inflationary spiral.

The joint reign of John Casimir and John Ernest II reflects the partitioned governance common among Ernestine Wettin branches, a dynastic habit that produced an almost bewildering variety of short-lived coinages across Thuringia in this period.
