25 Rupees

The Cocos (Keeling) Islands plastic coinage was introduced by the Clunies-Ross family, who administered the atoll as a private fiefdom and maintained a company-store economy in which islanders — predominantly Cocos Malay laborers — were paid in this proprietary currency, redeemable only within the islands. The system effectively trapped wages on-island. Australian authorities eventually dismantled the arrangement in the early 1980s, buying out John Clunies-Ross and integrating the territory fully into the Australian dollar zone in 1984.

The plastic tokens were issued in multiple denominations across several colors; the 25-rupee piece in red sits at the higher end of the series.
