1 Crown - Elizabeth II Queen Elizabeth's 70th Birthday

The Isle of Man has long operated its own coinage program independently of the Royal Mint, issuing commemorative crowns with unusual frequency since the 1970s under the Pobjoy Mint. By the mid-1990s, the volume of Manx commemorative issues had grown to the point where collectors frequently struggled to distinguish genuinely limited strikes from broadly distributed bullion-adjacent pieces. This coin marks Elizabeth II's 70th birthday in 1996, one of several milestone birthday issues the island produced across her reign.

The KM#582a suffix denotes the sterling silver variant, issued alongside a cupro-nickel version — the standard split that Pobjoy used to serve both the collector and circulation markets simultaneously.
