A coin collector has revealed the particular 50p coin which could be worth up to 90 times its 50p value, between £40 and £45.
TikTok account CoinCollectorUk has pointed out one specific EU presidency inspired 50p coin is one of only 109,000 ever produced, making it one of the rarest 50p coins ever.
Its uniqueness lies in that it is dated with two years, 1992 and 1993, when the UK was president of the European Council of Ministers, and the Single Market was completed.
Designed by Mary Milner Dickens, the coin depicts a conference table from above surrounded by 12 chairs, illustrating the EU's Council of Ministers. The design features the UK at the top to signify its presidency at the time, as well as 12 stars for each member of the EEC.
One estimation by collector Crawley Coins puts the coin's value at up to £60, 120 times its value. CoinCollectorUK also revealed that another 20p coin could be up to 300 times its value.
Released by the Royal Mint in 2008, these 20p coins could be worth up to £50, due to an error in their manufacturing.
The key to identifying one of these 20p pieces is to look out for a missing date, according to CoinCollectorUK. This occurred after a re-design, after a 2008 change which put the date on the heads side instead of the previous tails side.
The coins were incorrectly minted, using the old version of the heads side, which has no year date and the new version of the tails side which also has no year date.
The coins are called ‘mules’ due to their mismatched sides and there may be up to 250,000 in circulation. This was the first dateless coin in the UK since 1672 and therefore is very rare and valuable.
A ‘mule’ coin was also released in 1983 when the Royal Mint wrongly struck the 2p piece with the text 'new pence' instead of 'two pence'. This 1983 2p mule is worth hundreds because hardly any of these particular coins ever reached the public.
