Mauritius switched from paper to polymer for this denomination in 2024, joining a growing number of island economies that have moved to the substrate primarily for durability in humid climates — polymer notes typically last two to three times longer in heavy circulation than their cotton-paper equivalents. De La Rue has been the dominant supplier to the Bank of Mauritius across multiple series, so the relationship here is long-established rather than newly tendered.

Pick 65A is the inaugural polymer entry for this denomination in the standard catalogue, which gives it some reference significance regardless of eventual scarcity.
