I was there with my wife and 1 year old so did not get to spend as long as I would have liked, we were there about 90 minutes or so. I did manage to have a chat with a few people running some of the stalls there and explained I was new to the hobby and that I was primarly browsing to get a feel for the coin fair and the people there. I will be going again next month all being well. It would be great to meet you! I think my main issue is that the grading system seems so subjective that people opinions seem to vary a great deal, not to the degree off some of the bandits on ebay, but still enough to baffle a newbie like me. I did make a purchase but that was purely for my silver stack. Regarding your tray, I probably did miss. I tried to look at every table at least once (subject to it not being croweded out) and where I could spend some time looking through what was there I did. My lack of experience and knowledge ultimatly probably stopped me buying something there and then.
