Ceylon's transition from silver to nickel-brass coinage in the smaller denominations came in the early 1950s as global silver prices made the old alloy economically untenable for circulation pieces. This 25-cent type continued well past George VI's death in February 1952, with the same obverse dies used through a transitional period before Elizabeth II coinage was introduced — meaning examples dated after 1952 are a quiet anachronism, struck under a king already dead.
