50 Pence - Elizabeth II HRH Duke of Edinburgh - 2000's

The Isle of Man has long issued commemorative 50 pence pieces outside the mainstream Royal Mint program, giving the Manx government latitude to produce tributes the UK itself would not strike. This piece honoring Prince Philip was almost certainly issued in anticipation of — or response to — his death in April 2021 at age 99, part of a broader wave of Manx memorial coinage that flooded the market that year.

Philip held the title Duke of Edinburgh from 1947 until his death, a tenure of nearly 74 years — the longest any person has held that specific dukedom.
