More Info

In 2008 The Royal Mint changed the design of the circulating coins from the Royal Emblems to the Royal Arms. To accommodate the change, the year of the coin was moved from the reverse to the obverse. 

A batch of twenty pence coins were struck using the incorrect old obverse, meaning the coin had no date on it. The Royal Mint reports that fewer than 250,000 of these error coins were produced out of a total mintage of 136 million. 


The obverse is the Ian Rank Broadley portrait of Queen Elizabeth II. This is the fourth coinage portrait which was used from 1998 up until 2015. 



The reverse shows a section of The Royal Arms, as designed by Matthew Dent. When the circulating coins are placed together, they make up The Royal Arms. 

The text reads TWENTY PENCE.
