1000 Rupees Bank of Mauritius

The Bank of Mauritius has issued gold commemoratives sporadically since the 1970s, typically tied to national anniversaries or significant constitutional moments. The 2017 issue falls in the fiftieth anniversary year of Mauritian independence, declared on March 12, 1968, when the island severed its final formal ties with Britain after over 150 years of colonial administration. Mauritius had been one of the more economically productive British colonial possessions in the Indian Ocean, its sugar industry dominating export revenue well into the postcolonial period.

The .9166 fineness places this squarely in 22-karat gold — the same standard used for British sovereigns.
