5 Pounds - Elizabeth II The Queen Mother's 90th Birthday

Struck to mark Elizabeth Bowes-Lyon's 90th birthday in August 1990, this issue belongs to a wave of commemoratives that flooded Commonwealth mints in the late 1980s and early 1990s as peripheral territories discovered crown-sized silver pieces as a revenue stream. The Falklands' participation carried particular political weight — the islands had been defended at significant cost only eight years earlier, and the Royal Family's symbolic value to the territory remained acutely felt in Port Stanley.

The .925 specification and 28.28g weight place this squarely in the poured-to-a-formula commemorative mold of the period, struck by Pobjoy Mint on behalf of the islands.
