24 Mariengroschen - Christof Frederick and Jost Christian Ausbeutegulden

Stolberg's silver output in this period came almost entirely from the Kupferberg and Roßtrappe mines in the Harz — "Ausbeutegulden" (or Ausbeute coinage) being the term for coins struck specifically from mine-yield silver, a practice that let ruling houses advertise their mineral wealth to creditors and trading partners simultaneously. The joint reign of Christof Frederick and Jost Christian, two brothers administering an already-fragmented county, lasted until Jost Christian's death in 1738, giving this type a production window of over three decades — long for an Ausbeute issue, which typically tracked boom cycles rather than political tenures.
