5 Pounds - Charles III Christopher Wren, Silver Proof

Wren's commission for St Paul's Cathedral came only because the Great Fire of 1666 leveled the medieval structure that had stood on Ludgate Hill for centuries — a catastrophe that gave him the blank slate his earlier rebuilding proposals had been denied. The Cathedral took 35 years to complete, from 1675 to 1710, making it the only major English cathedral built under a single architect's continuous supervision.

Guernsey's involvement is purely contractual — the island has issued commemorative five-pound pieces for the British market through the Royal Mint and private licensees for decades, with no particular local connection to the subject.
