We’re being encouraged to check our change as an incredibly rare 50p coin has surfaced, featuring an error that significantly increases its value. This rare coin, issued by the Royal Mint in 2017, is believed to have very few specimens with this defect in circulation, making it highly collectible.
Due to its rarity, some of these coins have fetched prices exceeding 100 times their face value on platforms like eBay. Let’s dive into the details of what makes this 50p coin so valuable, how to identify it, and other rare coins you should look out for.
Spotting the Rare 2017 Sir Isaac Newton 50p Coin
According to TikTok coin expert Coin Collecting Wizard, one of the most sought-after coins is the Sir Isaac Newton 50p, first released in 2017. To identify this rare version, collectors should inspect the obverse (front) side for extra lines across Queen Elizabeth II’s portrait.
These lines are believed to have been caused by a die clash during the striking process, resulting in what looks like whiskers raised above the coin’s surface. Unlike typical scratches or grooves, these lines stand out slightly, making this coin distinct.
Though the exact number of error coins in circulation is unknown, they are thought to be extremely rare and have been sold for impressive sums on the secondary market.
Factors That Increase a Coin’s Value
The 50p coin is one of the most beloved and collected coins in the UK, especially due to its unique heptagonal shape, which allows for artistic and commemorative designs. But what exactly makes a coin valuable?
- Low Mintage: The fewer coins produced, the higher their desirability among collectors.
- Unique Design: Special editions celebrating significant events or historical figures often attract collectors.
- Condition: Coins in mint or uncirculated condition are generally worth more.
- Errors or Variations: Coins with striking errors, such as misprints or die clashes, can command significant premiums.
- Market Demand: How and where the coin is sold—whether on online platforms or through reputable dealers—can also affect its price.
