A 50p coin that celebrated the 250th anniversary of Kew Gardens rose in value after the Royal Mint announced it was the rarest commemorative coin design ever released into circulation in the UK.
There were 210,000 of the coins made and distributed in 2009 to mark the Royal Botanic Gardens' anniversary.
To put that figure into perspective, there were 22.7 million 50 pence pieces released with the shield of the Royal Arms in 2008 and 7.5 million created to celebrate 100 years of Girlguiding in 2010.
Right now even used 50p Kew coins are selling for around £40!
Do you have one?
The Royal Mint is encouraging people to check their change to see if they have the ‘incredibly rare work of art’ in there.
It says one in 300 people in the UK could have one, just 0.32% of the population.
The coin features a design by Christopher Le Brun.
On the face is the famous pagoda from the Royal Botanic Gardens encircled by a vine with the dates ‘1759’ and ‘2009’ and the word ‘Kew’ framing the design.
The Royal Mint anticipates the coin will now disappear from circulation as people hang onto the valuable coin and wait for its value to rise.
Shane Bissett, Director of Commemorative Coins at The Royal Mint, said: "Now that people know just how rare this particular coin is we expect them to disappear from circulation fast."

Selling your 50p on eBay
Prior to the Royal Mint announcement the Kew 50p coin was selling for around £7-£12 on online auction site eBay.
There are now over 1,200 listings for the coin.
Many auctions are starting at 99p for used or 'circulated' coins, while some sellers are asking as much as £300 for unused or 'uncirculated' 50p Kew Gardens coins in their original sealed plastic case.
Circulated coins tend to go for around the £50 mark.
But so far the most a 'circulated' 50p Kew Gardens coin has gone for on eBay that I could find is £183 on 21st February 2014 – 366 times its original value. While the most an 'uncirculated' version in its original packaging has gone for is £310 on the same day.
