A man has just sold a rare 2p piece on Gumtree for the incredible sum of £485.
The coin was minted in error in 2015 after being accidentally struck onto the nickel-plated steel base of a 10p instead of the copper-plated steel used for 2p coins, WalesOnline reports .
It was sold on January 3 to a coin collector in Fife.
The Royal Mint, which makes as many as four million pennies a day, rarely lets these error coins slip out. That makes them extremely rare - and as such valuable.
Posting next to a picture of the curious coin, listed as "Silver 2 pence coin minted in error", the seller wrote: "Extremely rare coin which I bought three years ago.
"The price is set and will not become an auction as it's being sold through necessity."
He added that he bought it from a friend in Thames Ditton, Surrey in 2018.
It's not the first time someone's found a 'silver' 2p either.
Back in 2016, one sold for £1,350 after being donated to charity by an anonymous donor.
The 2p was almost thrown away, after being thought to be a fake, but after Royal British Legion volunteers in Wiltshire took it to a bank, they discovered it was incredibly rare.
At the time, Charles Vernon, treasurer of the legion in Malmesbury, said he and his wife spotted the "odd" coin when the collection was being counted.
"When we tried to put it in the 10p pile it didn't fit - it was an anomaly and stood out," he said.
It's since been handed to The Westminster Collection, a company which specialises in collectable coins and stamps.
Another "silver" 2p coin sold for £1,357 at auction in 2014 - and a few more are believed to be out there, sitting in jars of foreign currency, piggy banks or piles of old, unusable money.
