The young Princess Elizabeth fell for the dashing Philip during a visit to the Royal Naval College in Dartmouth in 1939. Separated while Philip served at sea, they were reunited after the war and announced their engagement in 1947. That November they were married at Westminster Abbey, and 70 years later they celebrate the first platinum anniversary in British royal history.

Such a significant personal milestone deserves a fitting celebration, and the Piedfort coin has a majestic history. Once the preferred gift of royalty, today these double-thickness pieces are issued to celebrate important events and anniversaries. Struck in sterling silver, the coin’s Proof finish enhances every detail of Etienne Millner’s combined portrait and John Bergdahl’s equestrian design.
