5 Pounds - Elizabeth II Royal Scot, Silver Proof Gold plated

Alderney, the smallest of the four main Channel Islands, issues coins under a royal warrant but holds no independent monetary policy — these pieces are legal tender on the island in theory, though none circulate. The 2006 Royal Scot issue commemorates the Royal Scot locomotive, the LMS Class 7P that entered service in 1927 and became one of the defining express engines of the interwar British railway network.

The gold-plated silver variant occupies a curious middle tier in the production hierarchy, below the solid gold strikes but carrying a visual premium over plain silver proofs — a format that became increasingly common in commemorative issues of this period as mints sought additional price points within a single release.
