5 Céntimos Castellbell i el Vilar

One of hundreds of municipal emergency issues produced across Republican-held Catalonia during the Civil War, when the collapse of small-denomination coinage left local governments scrambling to keep retail transactions functioning. Castellbell i el Vilar, a small textile-mill municipality on the Llobregat river, issued its own emergency scrip like dozens of comparable towns — the Generalitat had authorized local authorities to do so, but standardization was never really enforced.

At 50 × 43 mm, this is genuinely tiny even by the standards of wartime Catalan municipal notes, which were themselves already modest. Thick card stock was a common workaround when proper banknote paper was unavailable.
