The Peter Rabbit 50p coin was released by The Royal Mint in 2016 as part of the commemorative Beatrix Potter 50p coins.
Coin enthusiasts, The Great British Coin Hunt, spent 400 of the coins in shops around the country, which is how some of them ended up in circulation.
The coin, designed by Emma Noble, is part of a whole series that is sought after by collectors.
One seller from Somerset has listed the coin on the eBay online marketplace for £2,000 - 200 times the Royal Mint's valuation, which is valued at around £10.
Over the years, The Royal Mint has made different collections of the coin due to its popularity. The rarest Peter Rabbit 50p coin is from 2018, with only 1,400,000 minted.
There are plenty of Peter Rabbit 50p coins sold on eBay - with commemorative coins in boxes selling for up to around 30 pounds. Some circulated coins sell for just a few pounds, depending on the condition of the coin.

If you have a rare coin, you might want to follow in the footsteps of others and sell it. However, selling a coin on eBay is never guaranteed, and a coin is only ever worth what someone is willing to pay for it.
This means you could potentially make a lot of money from a coin, but it is not guaranteed.
If you are a collector, then you should also keep in mind that fake coins can appear online too, so always be wary before handing over any money.
