Rare £2 coin minted in 2007 could be worth 17 times its face value - so check your change

The rare £2 coins, minted in 2007 have the date 1807 engraved on them and recently two have sold online for £28 and £25.74.

A specific £2 coin could be stashed away in your change and it might just be worth 17 times its face value.

The rare £2 coins, minted in 2007, have the date 1807 engraved on them and recently two have sold online for £28 and £25.74.

The coins were part of a minting to commemorate 200 years since the passing of the Slave Trade Act of 1807 - which made it illegal to trade slaves in the British Empire.

But the reason these specific coins sold for so much is because they are part of the Piedfort silver edition, which makes them especially interesting to collectors.

There were 3,990 of the Piedfort silver 1807 coins issued in total.

"In a standard weight of 24.00 grams, this £2 is struck in .925 sterling silver with a band of fine gold plating around the edge reminiscent of the Two Pounds in your change," the Britannia Coin Company explained on their website.

The Piedfort silver 1807 coins were originally sold for around £49, whereas 8,445,000 of the regular 1807 coin were made, and are worth their £2 face value, the Sun reports.

The silver coins are worth more because they were struck multiple times meaning they have better detail and quality, as well as their scarcity.

The coin features a broken chain motif with the zero forming part of the chain.

On the other side is the head of Queen Elizabeth II and it also features the inscription "Am I Not A Man, And A Brother".

Meanwhile, a coin expert says there is a detail on some 20 pence pieces which can make it hundreds of times its normal value and known as the “holy grail”.

In 2008 some 20p coins were minted with the wrong dye and so, as a result, they have no dates.

The mix up was the first time in three centuries a coin had entered circulation without a date.
