Have you got a 20p worth £50 in your pocket?

The Royal Mint of the United Kingdom produced in error about 200,000 coins without a date. They are the first undated British coins to enter circulation for more than 330 years.

The date on the new 20 pence was moved from the 'tails' to the 'heads' side when all country's coins from the 1p through to the £1 were redesigned last year. So, 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.

The Royal Mint confirmed that "a small number of new-design 20p coins have been incorrectly struck using the obverse from the previous design, resulting in these coins having no date", but added they were legal tender and could be used as normal.

The error has caused a great deal of excitement among coin collectors because the Royal Mint, in Llantrisant, South Wales, is normally so careful about the manufacture and release of coins into circulation. No one knows how much the undated 20p is worth. However, The London Mint Office, which is a private company with no connection to the Royal Mint, is offering £50 a time to anyone who has one.

Notes

In 1983, the Royal Mint made an error with the 2p piece and struck some with the wording 'new pence' rather than 'two pence'. The 1983 2p coin is currently worth a few hundred pounds, however its value was enhanced because only a very few of these reached the public.

Coin expert at the London Mint Office, Nick Hart, said: "Mistakes like this not only fascinate people but also have considerable value-increase significance. We believe this extremely rare error will certainly get the public looking at the coins in their pockets again and noticing the excellent new designs launched by the Royal Mint on our coinage."
