History and design
This is a collector version of the 10 Pence - Elizabeth II – K - King Arthur. The history below is that coin's; the mintage, varieties and collecting notes on its page do not apply to this strike.
King Arthur is the letter K in the Royal Mint's A to Z 10p series, 26 circulating coins revealed on 1 March 2018 under the title The Great British Coin Hunt: Quintessentially British A to Z. Coin World reported that the themes were chosen after a poll of UK residents in 2017. Change Checker describes the set as the first commemorative UK 10p coins.
The Royal Mint's page for the coin calls Arthur one of the most famous characters of myth and legend. In the legend he lived in the mythical city of Camelot and formed a Round Table of some 150 knights. The Mint is careful about the history: it says his existence has been widely debated, and that the most that can be said is that a man named Arthur, or Arturus, led warriors who resisted the invading Saxons, Jutes and others in the fifth and sixth centuries AD.
The Royal Mint's circulating figures give 220,000 for the 2018 date and 84,000 for 2019, a total of 304,000. Both figures are the standard ones for the series.
The reverse shows King Arthur and the Knights of the Round Table circling a large letter K. The Royal Mint credits the reverse to The Royal Mint Team. Coin Hunter names an individual designer, P J Lynch, which the Mint's own pages do not confirm.
The obverse has the fifth portrait of Elizabeth II by Jody Clark, with the denomination and the date. The coin is nickel-plated steel with a milled edge, like every 10p made since January 2012.
