1 Crown - Elizabeth II The Battle of Agincourt, Silver Proof

Agincourt was fought on 25 October 1415, and Henry V's outnumbered English and Welsh force — estimates range from 6,000 to 9,000 men — defeated a French army perhaps three times its size, with English casualties counted in the dozens against French dead numbering in the thousands. The victory owed much to the longbowmen and the sodden ploughed field that stalled the French advance.

The Isle of Man Treasury has issued commemoratives under Crown dependencies' broad minting latitude, frequently licensing historical British subjects regardless of direct Manx connection. The 2006 date marks the 591st anniversary — no particular round number, suggesting this belongs to a broader medieval battles series rather than a milestone occasion.
