25 Pfennig Wohltätigkeitsbazar

Castrop's 1921 charity bazaar note is among the more unusual applications of the Notgeld phenomenon — issued not to relieve a coin shortage in commerce but to fund a municipal charitable event directly. The face value functioned essentially as a admission or purchase token, with redemption tied to the bazaar itself rather than to any ongoing circulating obligation. Whether the city ever formally redeemed outstanding pieces after the event is unrecorded, which likely accounts for the survival rate being higher than for workhorse emergency issues of the same period.
