People have been advised to watch out for three extremely valuable coins that remain in circulation. These particular pieces could collectively be worth over £43,000. However, as reported by The Mirror, each must possess specific characteristics or dates to command such high prices. A specialist known as the Coin Collecting Wizard outlined what you need to look for in a video shared on TikTok. He emphasised the significance of the Brexit 50p piece, the Olympics aquatics 50p coin, and a Lord Kitchener £2 coin, while explaining the precise details to search for. Firstly, the expert explained more about the Brexit 50p coin that could fetch up to £40,000. This piece was struck to mark the date Britain departed the EU on January 31, 2020. But numerous examples were manufactured before this date bearing what became an erroneous date, as Brexit had originally been scheduled for the previous year. Consequently, collectors should hunt for the specific dates of March 29, 2019, or October 31, 2019. The coin's reverse (tails) side is readily identifiable, displaying the inscription "peace, prosperity and friendship with all nations". The obverse (heads) side bears the portrait of Queen Elizabeth II. The specialist commented: "This is the Brexit 50p coin from 2020. "Now before you get excited it's actually a different date you are looking for. If your Brexit 50 pence says anything other than 31 January 2020, then you have found a super rare coin estimated to be worth £40,000." He then went on to discuss how a 50p piece from 2011 could potentially fetch up to £2,000. This particular coin, known as the Olympic aquatics coin, bears the image of a swimmer. However, the real treasure is an earlier version of this coin where the lines symbolising water cover the swimmer's face. "This one is 50 pence from 2011, part of the Olympics set you can find in your change," he explained. "If you find this aquatics 50p but there are lines over the swimmer's face then you have just found a rare first edition coin worth £2,000." Lastly, he disclosed that a £2 coin from 2014 could be valued at £1,000. The reverse side of this coin features an image of Lord Kitchener, commemorating 100 years since the beginning of the First World War. However, only a misprinted version of this coin holds any significant value. He added: "This is a two pound coin from 2014 known as the First World War Lord Kitchener. Again just like the other coins, you are looking for something different. "If you were to flip this coin over and it doesn't have the words 'two pounds' on the obverse, then you have found the rare mule error worth over £1,000."
