Like many other mints, the Royal Mint issues bullion coins in precious metals, having much higher intrinsic value than their face value. The five ounce (5 oz) silver coins are denominated as ten pounds (£10).
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 smaller denominations with the same reverse designs.
This coin type is the first from a series of ten coin designs known as the Queen's Beasts.
The Queen's Beasts are British coins issued by the Royal Mint in platinum, gold, and silver since 2016. Each of the coins in the series features a stylized version of one of the heraldic Queen's Beasts statues present at the coronation of Queen Elizabeth II representing her royal line of ancestry. It was announced that engraver Jody Clark will design the entire series; he is best known for also designing the Queen's Fifth definitive portrait, which is on the obverse of the coins.
The Queen's Beasts heraldic statues representing the genealogy of Queen Elizabeth II stood in front of the temporary western annexe to Westminster Abbey for the Queen's coronation in 1953. Each of The Queen's Beasts consists of an heraldic beast supporting a shield bearing a badge or arms of a family associated with the ancestry of Queen Elizabeth II. They were commissioned by the British Ministry of Works from sculptor James Woodford. The statues were uncoloured except for their shields at the coronation. They are now on display in the Canadian Museum of History. There are other statues of the Queen's Beasts, sometimes referred to as the King's Beasts, at Hampton Court Palace and Kew Gardens in London, and on the roof of St George's Chapel, Windsor Castle.
The Lion of England is the crowned golden lion of England, which has been one of the supporters of the Royal Arms since the reign of King Edward IV (1461 - 1483). It supports a shield showing the Arms of the United Kingdom as they have been since Queen Victoria's accession in 1837. In the first and last quarters of the shield are the lions of England, taken from the arms of Richard I "The Lionheart" (1157- 1199). The lion and tressure (armorial border) of Scotland appear in the second, and the harp of Ireland is in the third.
