A batch of 20p coins accidentally issued with no date on them
could be worth £50 each

The date on the new 20p was moved from the ‘tails’ to the ‘heads’ side
when the country’s coins were redesigned last year.

The coins without a date were created by accidentally pairing up the new
‘tails’ side with the old ‘heads’ – meaning no date appeared at all.

somewhere between 50,000 and 200,000 of the ‘faulty’ 20p coins
are thought to have entered circulation.

They are still legal tender,but coin collecters would be willing
to pay much more than their 20p face value.
