Elizabeth II, £1 (Northern Ireland Pound) 1991 Proof Sterling Silver
A palindrome is a number that reads the same from right to left as it does from left to right. In this case, the date is 1991 whichever way you read it. In 1991 the Royal Mint issued a special collectors edition of the Pound coin, it was struck in Proof Sterling Silver. It had a flax plant on it to honour Northern Ireland. These 1991 Sterling Silver Proof Pounds are rather handsome and have the so-called Maklouf bust of the Queen on them. You too can be a VIP when you order one of these VIP coins.
