25 Rupees - Elizabeth II Conservation

Mauritius issued this piece as part of the wider Conservation series coordinated across numerous Commonwealth nations in 1975 — a project tied to the IUCN and WWF's push to leverage numismatic collecting as a funding and awareness mechanism for endangered species programs. The effort produced a remarkable breadth of silver issues from countries that rarely struck commemorative coinage, and Mauritius was among the more enthusiastic participants.

The .925 standard aligns with the series' deliberate positioning as a collector product rather than circulating currency — none of these were ever intended to pass hands at face value.
