1 Centavo

Chile's 1975 centavo issues were economic ghosts almost from the moment they were struck. The Pinochet government's post-coup monetary reforms had already set the stage for runaway inflation that would, within a few years, render the entire centavo denomination functionally worthless. The aluminium alloy choice reflected not design preference but raw material desperation — copper was too valuable to waste on the smallest denomination.

KM#203 belongs to the short window before the 1975 monetary reform replaced the escudo with the new peso at a rate of 1,000 to one, wiping centavo-denominated coins from circulation permanently.
