The £2 British coin celebrated its 25th birthday just last year, coming into circulation in 1998.

According to Coinhunter, there are 63 different designs for the iconic bi-metal £2 coin and around 37 of them are in circulation and can be found in your spare change.

But what are the rarest coins to look out for?

Well, in the midst of all the cost-of-living chaos, you might be holding onto a £2 coin that is in fact worth a heck of a lot more.

The other 26 designs were issued as "commemorative coins" and were not put into circulation so will sadly not appear in a random coat pocket.

In May, Change Checker released its most recent "scarcity index" which details the coins that are most sought-after coins in circulation over the last three months.

The list is broken down into three categories: the rarest 50p coins, and A-Z of 10p coins and £2 coins currently in circulation.

The top three rarest £2 pieces are once again all from the Commonwealth Games 2002 collection.

Here is a list of the £2 coins you should be keeping an eye out for.

Rarest £2 coins - worth up to £35

The XVII 2002 Commonwealth Games £2 coins were created to mark the seventeenth games, hosted in Manchester from July 25 2002.

Currently, the most sought-after is the Northern Ireland version, followed by Scotland and then England.
