Thought l'd put this in the NAAFI as more people have a look in here. Apparantly there is a batch of new 20p piece with out a date on them. As it currently stands the London Mint office will give you Â£50 if you return it to them. However it will no doubt be worth more in the long run! There are roughly 200,000 of them in circulation and none of the buggers are in my pockets, change jar or down the back of my sofa! On the new 20p the date is on the same side as Her Majestys head If you find one, you could look at this website www.undated20p.com Full story here http://uk.news.yahoo.com/5/20090629/tuk-minted-lucky-20p-owners-could-get50-45dbed5.html 200,000 of the buggers one of us lot is bound to get one!
