There are some rare 50p coins in circulation at the moment - including one variety in particular that's worth a whopping £140.
The special coin was released back in 2009 to celebrate the 250 years since Kew Gardens in London opened back in 1759.
According to the Royal Mint, approximately 210,000 of these were made, and it has an image of the beautiful Chinese Pagoda at the Gardens on one side with the classic Queen's head on the other.
