What's with these coins? I've been coming by a lot of coins recently with a date written on them (19/5/2013 which is March 13th 2013 by our calendar if you want to know), some with a message saying "Expect us" as well as the date. Usually I wouldn't pay any attention to this kind of thing but it's concerning me simply because of the number of coins I've seen it written on. I live in England and have come across them in the different areas of London. Is there something going on that I don't know about? Sorry if I'm stressing over nothing, but it's just freaking me out a bit :S
