50 Pfennig Alte Diele

Alte Diele was a well-known tavern and meeting place in St. Pauli, and this 50 Pfennig note is a piece of Hamburg Notgeld — emergency small change issued by local businesses and municipalities during the acute coin shortage that gripped Germany in the early 1920s. With the Reichsbank unable to keep fractional coinage in circulation fast enough to outpace inflation, thousands of private issuers stepped in. A tavern issuing its own currency was entirely unremarkable at the time.

Locally printed, redeemable only at the issuing establishment, and typically withdrawn from circulation within months — survival depends almost entirely on whether collectors pulled them before redemption.
