10 Céntimos Sadurní d'Anoia

Sadurní d'Anoia — better known today as Sant Sadurní d'Anoia, the centre of Catalan cava production — issued emergency fractional currency during the Spanish Civil War, as did hundreds of Catalan municipalities scrambling to fill the void left by a near-total collapse of small-denomination coinage. The Republican government had requisitioned metal for the war effort, and copper and nickel coins effectively vanished from circulation by mid-1936.

Turró catalogues thousands of these local Catalan issues; the sheer volume means individual pieces are often undervalued relative to their genuine scarcity, particularly at the lowest denominations where attrition from daily use was highest.
