Shoppers will have just six months to spend their old one pound coins after the new version is introduced in March.
The old coins will cease to be legal tender on October 15 and the government is now warning those with stacks of loose change sitting in savings jars or piggy banks to spend them or lose them.
But before you let your old £1 coins disappear, it’s worth checking to see if they’re worth more than their initial value.
Rare coins, such as the George V sovereign, have been going for up to £37,500.
Top five rare £1 coins which could make you an easy buck
The rarest one pound coin in currently in circulation is the Edinburgh £1 coin, issued in 2011.
There were 935,000 minted – and it’s one of four coins depicting the capital cities of the four constituents in the UK.
On eBay, a 2011 Edinburgh £1 coin is selling for £189.99.
The second rarest coin is the Cardiff £1 coin, which entered circulation in 2011.
The coin depicts the circular Coat of Arms of Cardiff and there were just 1,615,000 minted.
Although it’s selling for a lot less on eBay than the Edinburgh £1 coin, one Wales coin, gathering a lot of interest on eBay, is going for £39.99.
The third rarest is the England £1, and like the Edinburgh and Cardiff editions, was designed by Stuart Devlin, Goldsmith and Jeweller to the Queen.
There were 2,635,000 minted in 2010, and one is currently selling for £33.95 on eBay.
The next rarest is the Royal Arms £1, minted in 2008.
Although its design is more recognisable, there are only 3,910,000 in circulation.
This particular design, which could easily be confused with the Coat of Arms £1 coin issued in 2015, is selling for £22.95 on eBay.
The new £1 coin, the hardest yet to counterfeit, is the first to be introduced since 1983.
