You may have noticed recently there has been a fuss about some undated 20p coins that have entered circulation. Apparently The Royal Mint have been offering £50 for each coin, but I have seen them sell for a lot more on Ebay.
The coins that are valuable are the new 20p coins with the new design on one side, on the other side is the Queen's head. Both sides of the coin have no date. If you have a new 20p coin with the new design on one side and a date on the other side it's only worth 20p.
THANKS FOR LOOKING AT MY GUIDE!
