Rarest 10p coins - worth up to £10.50
The scarcity index of rare 10 pence pieces is made of the alphabet A to Z collection, released in 2018 and 2019 to celebrate all things British.
As you'd expect, there are 26 coins in the set to correspond with the 26 letters in the alphabet.
The rarest one from that collection is W for World Wide Web, launched to mark the invention of the internet.
Its design features the letter W surrounded by a spiderweb. Around 220,000 were issued for circulation in 2018, followed by a minting of another 63,000 coins in 2019.
The second rarest coin from the A to Z collection is R for Robin, which features a cute bird sitting on the letter R surrounded by snowflakes. When we checked online today, one of these had sold for £8 on eBay.
Like the W for World Wide Web coin, around 220,000 were issued for circulation in 2018 but a slightly higher figure of 64,000 were made in 2019.
Third on the scarcity list is Y for Yeoman Warder, launched to celebrate the guards of the Tower of London.
The design itself depicts one Yeoman Warder posing next to the letter Y. If you have one, the highest it'll likely go for on eBay is around £8.
Around 220,000 were circulated in 2018, while another 63,000 were released in 2019.
