10 Pfennigs - Berlin Vereinigte Kukuk Excelsior

Vereinigte Kukuk Excelsior was a Berlin-based umbrella and walking-stick manufacturer that issued notgeld tokens during the acute small-change shortage that gripped Germany in the early 1920s. Private firms across the country filled the gap left by insufficient official coinage, producing their own zinc and iron pieces redeemable at their own premises — a stopgap that the Reichsbank tolerated rather than sanctioned.

The Hasselmann reference places this squarely in the documented corpus of Berlin commercial notgeld, catalogued well after most of these tokens had disappeared from circulation.
