Like many other mints, the Royal Mint issues bullion coins in precious metals, having much higher intrinsic value than their face value. The quarter ounce (1/4 oz) gold coins are denominated as Twenty-five Pounds (£25).
The coins are legal tender but are not intended for circulation. They are targeted at bullion investors or collectors who appreciate the special editions as pieces of art. The coins are typically "one-year" types usually issued in parallel with other denominations with the same reverse designs.
This commemorative gold coin celebrates the Four Generations of the Royal Family.
The Royal Mint says:
"When His Royal Highness Prince George of Cambridge was christened, the joyful family celebration also marked a rare moment in the nation’s history. For the first time since Queen Victoria’s reign, the monarch, her son, grandson and great-grandson were all gathered together for the happy occasion. The Royal Family may fulfil extraordinary roles but they are known for maintaining decidedly ‘normal’ private lives, with the same dynamics as any other family.
As the growing family achieve an increasing number of personal and royal milestones, such as Her Majesty The Queen marking her Sapphire Jubilee, we join them in celebrating these special moments. Featuring a design by artist Timothy Noad that represents the four Windsor generations, this official UK coin has been struck in a quarter of an ounce of fine gold and finished to Proof standard. There are just 1,100 quarter-ounce coins available in this Limited Edition Presentation, each is presented in Royal Mint packaging with a booklet on this remarkable year for the Royal Family."
This quarter ounce gold coin was issued individually, in Proof FDC grade, in a mahogany presentation box, Royal Mint Product Code: UK18FGQG, with issue limit of 1,100 and issue price of £555.00. |
