The obverse of this 2017 coin features a double portrait of Queen Elizabeth II and Prince Philip in a poignant design by Etienne Millner. The inscription reads 'ELIZABETH II D G REG F D · PHILIP PRINCEPS ·' with '500 POUNDS' to the lower right.
On the reverse, a classic heraldic design by John Bergdahl combines the royal arms of the United Kingdom with the Duke of Edinburgh's personal arms. The words' 70 YEARS OF MARRIAGE · 2017 ·' are shown below.
Denominated at £500, this 1,000-gram coin is composed of 999 fine silver with a stunning proof finish. Among the largest coins produced by The Royal Mint, it measures 100.00 millimetres from milled edge to milled edge.
The Royal Mint authorized the release of just 500 one-kilogram silver proof Platinum Wedding coins in 2017, marking the 70th anniversary of the royal couple's marriage. This pre-owned example is supplied in the original presentation case with an inscribed plaque inside and a numbered certificate of authenticity.
