Thanks again, Midlands is a bit short notice for me, especially with 3 young children. I understand there is one in London in December, that might be one I can do, subject to how to manage the kids. I read on other threads to beware the grades at Croydon, I hope to get up to speed on that soon. I hadn't realised that you might need to understand how each coin wears to get that right and I guess I need some kind of magnifier, which I presume this site sells. Do you guys end up with an encyclopedic knowledge of values of each coin, or look them up when necessary, or I guess somewhere in between? Also do you end up finding a couple of dealers you trust and going mostly through them or constantly look across all dealers and auctions? Thanks Matt
