I'm fairly sure the George III was copper, although i would need to look again, and could easily obtain images. I will take some pictures, and if there are any significant dates or errors i should look out for please let me know. I don't really intend to sell any of these coins, it's just pure curiousity that is my drive in the interest in value. When i was a child my father used to let me look through his coin collection, i used to think it was fascinating, I'd love to do this with my own children at some point. I'd rather pass them on to future generations. My main problem is i have a large amount of old coins with no way of knowing which are worth keeping seperate from the rest. I tried searching for 1802 george 3rd coins, and cant find any on ebay. I also searched for the 1840 Victorian sixpence. These two coins stood out to me most due to the age of the first and the oddness of the 2nd. I have never seen a coin struck so the back is at a 180 degree angle from the front, whether these coins are common in Victorian times i am unaware as i was born years after these coins were taken out of circulation.
