The rarest and most valuable 50p coins in the UK, revealed by The Royal Mint

The 50 pence piece has become the most valued and collected coin in the UK, with many collectable designs appearing on its heptagonal canvas.

The Royal Mint coins, which date back to 1983, are rising in value thanks to a rare mistake in the wording on the coins.

The error makes them highly sought after by collectors, with just a small number of the coins being minted.

TikTok user @CoinCollectingWizard explained: “Did you know about the New Pence 2p coin worth £1,000? Don't worry though this one is 1971 and not the rare date.

"Want to know what rare New Pence coins to look out for, keep watching. After the design changed from New Pence to Two Pence in 1982, a mistake was made during production of a small number of 1983 coins."

The coins to look out for were struck with the old inscription of New Pence rather than Two Pence, but still carry the 1983 date.

“If it says New Pence on the reverse instead of the words Two Pence then you have found it.,” they explained.

“If you are lucking enough to find a 1983 New Pence 2p in your change, then it is worth around £1,000. You are more likely to find the coin in the 1983 Royal Mint set though as this is where the mistake happened."

What makes a coin valuable?

The 50 pence piece has become the most valued and collected coin in the UK, with many collectable designs appearing on its heptagonal canvas.

Its 27.5mm diameter makes it the largest of any British coin, and allows space for decorative pictures. It has often been used to commemorate big events over the past 50 years of British history.

The rarest coins tend to be of the greatest value, with the mintage (number of coins with each design made) being the fundamental attraction for collectors.
