Undated Twenty Pence mule (2008) - PCGS MS63

Great Britain, Undated Twenty Pence mule (2008) -

In 2008, the design of the twenty pence coin was changed, with the date being moved from the reverse to the obverse. That year, the mint erroneously struck and released twenty pence pieces minted with the old undated obverse dies and the new undated reverse dies. The result, sometimes called a mule, was a coin with no date. While not rare or even scarce (unlike Australia’s mule dollar from 2000), it featured prominently in popular media, so is keenly sought after by collector and non-collector alike. This example is in mint condition and graded PCGS MS63.
