A 50p coin released into circulation in 2009 has recently sold for £175 on eBay, after 50 bids were made for the heptagon shaped coin.
Only 210,000 coins with the distinctive Kew Gardens design were minted during its original release, featuring the famous Chinese Pagoda at the Royal Botanic Garden on the tails side.
However, before you start celebrating, the coin was re-minted in 2019 as part of a celebration of the 50th anniversary of the 50p. A much higher number of these were produced, so the 2019 version is far less valuable.
