Exact missing number that makes 20p coin 300 times more valuable – as rare change sparks eBay bidding war
A SIMPLE error on your 20p coin could mean it’s worth 300 times its usual value.
A batch of 20p coins from 2008 were mistakenly minted with no dates – and two have just sold on eBay for a whopping £107.
These undated coins, known as Undated Mules, were produced in November 2008 due to a change in The Royal Mint’s manufacturing process.
Whereas coins were previously dated on the “tails” side, that year the coin-maker decided to move dates to the “heads” side.
This resulted in a mix-up where no date at all was stamped onto 20p coins that month.
The Mules were the first undated coins to be put into circulation in more than 300 years.
Only 250,000 exist, out of 136 million 20p coins produced that month.
The eBay listing attracted five bids, before the final sale was completed on September 22.
Last month, a single one of these coins sold for more than £60 at auction, after attracting 14 bids.
The Britannia Coin Company website describes them as the “holy grail of change collecting”.
However, it is not the only 20p that could land its lucky owner a huge profit.
Last year, a 23-year-old discovered an error coin from 1982, likely worth hundreds.
And other loose change can see coin collectors get lucky too.
If your 50p has a sports-themed etching, it might be one of the ones designed for the 2012 London Olympics.
These vary in value from a handy few quid to thousands of pounds, with one error coin, featuring horizontal lines, selling for £1500 at auction this year.
