Thanks for all your input I haven't got any real interest in collecting, I have an interest in things in geaeral, age social inpact etc, that is about how far it goes - my gran tried very hard believe me! Here are my thoughts regarding this penny: The sea and particularly the rock appear to be more detailed, is this because it is different die or is it because one of my 2 coins was one of the first to be stamped and the other being the last to be stamped from a particular die? The teeth being worn around the date is a real pain and therefore can only be truely established by etching to show the difference in grain size (thick and thin stamping gives a different grain sizes) but this will deface the coin even further? I am resigned to the fact that it is virtually worthless because of this. Unless There are any other distingishing marks other than the date gap which I agree is a non starter because of wear I cannot see any alternative but to say I was nearly there and give it neck and move on to the other coins. If I put up my lists of coins (which I haven't completed yet) will you guys tell me if anything is worth investigating, also there are the foriegn coins? As I have said I was not given the whole collection, my gran always said she had the complete set from the mid 1800's and when my father gave them to me after her death, he said they are useless the best ones have gone. Thanks again Kel
