12 Mariengroschen - John Adolph

Bentheim-Tecklenburg-Rheda was a patchwork of territories assembled through inheritance and treaty across the sixteenth and seventeenth centuries, and John Adolph's rule in the 1670s came during the final decades before the county's absorption into larger regional powers. The 12 Mariengroschen denomination was a workhorse of northwest German commerce in this period, valued precisely because it bridged the gap between small change and the heavier Thaler-based system without committing to either.

Kennepohl's catalog of Westphalian coinage remains the primary authority for attributing this issue. County-level silver from this region in the 1670s survives in consistently low numbers.
