Rare minting error to spot on 20p coin that sold for 1160 TIMES its worth after sparking fierce eBay bidding war

“A valuable addition to any coin collection, this 50p denomination coin showcases iconic British cultural heritage with its portrayal of Sherlock Holmes.”

This comes after a rare Blue Peter Olympic 50p was flogged on eBay for £205.

The coin shows an athlete doing the high jump and was drawn by nine-year-old Florence Jackson after winning a competition on the kid’s TV show.
