1 Crown - Elizabeth II College of Arms, Earl Marshal

The College of Arms received its royal charter from Richard III in 1484, making 1984 its quincentenary — the direct occasion for this issue. The Earl Marshal, who presides over the College, is a hereditary office held by the Dukes of Norfolk; in 1984 that was Miles Fitzalan-Howard, 17th Duke. The Isle of Man Treasury was prolific in commemorative crown issues during the 1980s, targeting the collector market rather than circulation, and this piece was almost certainly never spent.
