The Royal Mint released 26 10p designs in March 2018, one for each letter of the alphabet from A for the Angel of the North to Z for the zebra crossing, and struck the same designs again dated 2019. They were the first commemorative 10p coins and went into circulation in small numbers, so a full set found in change is a long job. Both years are listed here.
104 coins are listed here, 52 in circulation condition and 52 brilliant uncirculated. Mintages run from 25,694 to 220,000 across the 104 coins with a known mintage. Values run from £2.00 to £15.75 across the 104 coins with a value. 13 Florin House collectors hold at least one of them. 104 estimated.
