5 Pounds - Elizabeth II Titanic, Silver Proof Issue

Alderney has issued commemorative coinage under Crown Dependency authority since 1993, and the Titanic centenary prompted a wave of such pieces across multiple jurisdictions in 2012. This particular issue came from the Royal Mint on behalf of the States of Alderney — a dependency of Guernsey with no independent central bank, meaning its commemorative program exists largely as a revenue exercise rather than a functional currency system.

The wreck lies some 370 miles southeast of Newfoundland, discovered by Robert Ballard's joint US-French expedition in September 1985.
