100 Dinara Akcija Drug Drugu, Crveni Krst Srbije

The "Akcija Drug Drugu" — roughly, "Friend to Friend Campaign" — was a Serbian Red Cross fundraising initiative that issued these coupon-style notes as donation receipts or pledge instruments rather than circulating currency. They occupy an awkward taxonomic space: not banknotes in any strict sense, but collected and catalogued as notaphilic material because they circulated hand-to-hand during charitable drives.

Red Cross charity scrip of this kind was common across Yugoslav successor states in the 1990s and early 2000s, often tied to specific humanitarian crises. The issuing body here is the national Serbian organization, distinct from the Yugoslav Red Cross that preceded it.
