25 Pfennig Alte Diele

Hamburg's St. Pauli district produced hundreds of privately issued emergency currency notes — Notgeld — during the inflationary chaos of the early Weimar years, and the Alte Diele was among the local establishments that printed their own small-denomination scrip when coin shortages made ordinary commerce difficult. Whether the Alte Diele was a restaurant, tavern, or retail shop is not definitively established in the standard references, but St. Pauli venue Notgeld of this type was typically redeemable only on the premises, functioning more as a token system than a true circulating currency.

The 25 Pfennig denomination places it squarely in the most practical range for counter transactions in 1921 — before hyperinflation rendered such fixed values absurd within months.
