5 Pounds - Elizabeth II Battle of Agincourt, Gold Proof

Alderney, a Crown dependency not part of the UK, has long issued commemorative coinage under license — producing pieces that circulate legally but exist almost entirely as collectibles. The 600th anniversary of Agincourt drew commemorative issues from several mints in 2015, and this gold proof sits in crowded company. What distinguishes the battle itself historically is Henry V's decision to execute French prisoners mid-engagement — a war crime by modern standards, debated by historians ever since as either tactical necessity or deliberate brutality.
