5 Pounds - Elizabeth II Quincentenary of the College of Arms

The College of Arms received its royal charter from Richard III in 1484, making 1984 the quincentenary the Isle of Man Government chose to mark — an unusual subject for a crown issue from a dependency with its own entirely separate heraldic traditions governed by the Lord Lyon in Scotland and, for Mann itself, loosely outside the English college's jurisdiction entirely. The choice reflects the broader British commemorative coin boom of the 1980s rather than any direct institutional connection.

Virenium, a proprietary copper-nickel-zinc alloy developed by the Pobjoy Mint, was the house metal for Isle of Man base-metal crowns throughout this period.
