Well I only know of two. That 1983 penny with the New Pence legend that caused a massive rumour, but you are unlikely to find any of them in your change!! Also, the 1985 £1 is pretty scarce, lowest mintage by a long way...
After Maser JMD started our new rules, I thought it would be fun to see what we've broken: No Swearing - there are younger coin collectors that post in the forum. - definitely! No Spamming - because its just plain annoying. - definitely: No Rude pictures/avatars - Same reason as swearing. - no No rasist pictures/comments - I am sure that you understand why. - no No nastyness towards other forum users - a joke once in a while is ok, and if you know someone who is constantly doing this then report them to an admin. - don't think so. Haven't we been good for Master JMD!
You're nitpicking again Oli... I am a boy, but you also mentioned small people, by that I assumed you meant children about my age, no? You also mentioned children of course, and being 15 you are still a child....
I thought you said in another thread that you did have an extremely rare coin Sylvester, no? The rarest coins I have are a threehalfpence with the date 1843/34 and a Gibraltar two quarts coin with the date 1842/1. They are both fairly rare, but I do not have an extremely rare coin though...
Why do you carry around a pocket piece anyway? I don't carry one around with me, but if you tell me the point of it I might start... If I was to start, I know just the coin...
If you are keeing your pennies in a box, then if one coin has verdigris it will spread to all the coins because they are touching. Store them seperately if you do not want it to continue spreading!
