The U Union Flag 10p turns a familiar flag into a striking pattern in metal. Its strong lines make it an appealing choice for a collection of British symbols, as well as the U space in your alphabet.
Three crosses in one flag
The modern Union Flag combines the cross of St George, the saltire of St Andrew and the saltire of St Patrick. That combined design dates from 1801.
On the coin, raised lines carry the pattern instead of red, white and blue. The large U sits within it, giving the reverse a bold, graphic look.
2018 or 2019?
The design was issued in both years, with circulation mintages of 220,000 for 2018 and 84,000 for 2019. The first date belongs to the original alphabet release. For a 2019 album, choose the later date with the same flag design. These are circulation counts, separate from collector editions; they do not establish how many Uncirculated coins are available to buy.
The lower 2019 figure makes that date scarcer in circulation; it does not guarantee a higher selling price.
Union Flag or Union Jack?
Union Flag is the official coin name, though Union Jack is another familiar name for the flag. They refer to the same U design, so you can concentrate on choosing the year you want.
Its recognisable subject makes U a straightforward choice for a gift, particularly for someone interested in flags or British design.
Symbols that work together
H: Houses of Parliament adds another emblem-led design, while the carriage on J: Jubilee brings a royal celebration to the group. Start with those three, or give U its place in a complete dated A–Z.
Choose your 2018 U Union Flag 10p or 2019 U Union Flag 10p. Both Union Flag dates are offered in Uncirculated condition.

Circulation mintage: 220,000 for 2018 U and 84,000 for 2019 U. These low circulation figures explain the rarity of these dated coins in change. They exclude collector editions and do not count the Uncirculated coins available today.
The alphabet series launched in March 2018. The 2019-dated circulation rollout began in February 2019, according to the original programme FAQ. For bags, cards and albums, see our packaging comparison.
