4 Rare UK Coins You Should NEVER Spend — Check These Queen Elizabeth II Coins Before It's Too Late

Before you spend or clean another old British coin, examine it carefully. A strange colour, unusual weight, missing detail, or major striking mistake could reveal a genuine collector discovery. In this Mint Vault USA video, we explore four fascinating UK decimal coins connected with Queen Elizabeth II and Britain’s historic change to decimal currency. These ordinary-looking pieces may show circulation wear, scratches, flattened details, and natural toning, but the right authenticated Mint error could create serious collector interest. The coins featured in this countdown are: 1978 UK New Pence 2p Coin1968 UK Ten New Pence Coin1979 UK Five New Pence Coin1979 UK Fifty New Pence Coin Discover the history behind Britain’s early decimal coins, including the large 5p, 10p, and seven-sided 50p designs. Learn how these coins circulated beside older British money, why the words NEW PENCE are normal on certain dates, and how to recognise the classic portraits and reverse designs created by Arnold Machin and Christopher Ironside. We also examine important collector clues, including off-centre strikes, clipped planchets, wrong-metal errors, wrong-planchet strikes, die cracks, weak details, possible doubling, unusual coin weights, natural toning, and post-Mint damage. Watch until the end, because the final large Britannia 50p has the widest surface, the most unusual shape, and several areas where a genuine production error could be hiding. Remember, an old date or worn surface does not automatically make a coin rare. Most circulated examples are ordinary historic coins. Exceptional values usually apply only to authenticated Mint errors, scarce varieties, proof coins, or pieces preserved in outstanding condition. Never polish or chemically clean a potentially collectible coin. Cleaning can remove its original surface, create permanent scratches, and reduce collector interest. Handle coins by their edges, store them in safe non-PVC holders, and consider professional evaluation from a reputable dealer, specialist auction house, NGC, PCGS, or the Royal Mint Museum.
