5 Pounds - Elizabeth II Sovereign of the Seas

The Sovereign of the Seas was an English warship launched in 1637 under Charles I, built by master shipwright Phineas Pett at a cost so extravagant — roughly £65,000 — that it triggered a constitutional crisis. The ship tax levied to fund her construction, known as Ship Money, was extended from coastal counties to inland ones in defiance of precedent, fueling the grievances that fed directly into the English Civil War.

Jersey's commemorative crown-sized issues of this period were struck by the Royal Mint to standard crown specifications.
