I often wondered whether some sort of interactive grading website would be good... maybe like a game or quiz. It could show you a coin, you select what grade you think it is, it tells you how you fit in with opinion so far (or expert opinion, or whatever). There could be a link to somewhere to write comments where people could discuss the grading. In fact, what I have described could probably be done with the voting mechanism on the forum, although it would get a bit cumbersome with a thread for each type of coin in each grade. Still, it could provide a useful resource for us all (especially for less common types) and it would be interesting to see the things that different people look for when grading. I like this idea and think there could be some mileage in it. Have a feeling though all graders should be anonymous, as there could be a tendency to undergrade out of sheer machismo! I don't think undergrading is likely to be a problem. All people have to do is be honest with themselves, look at the coin objectively and properly scrutinise it for wear, then take an ego-free path and give an accurate assessment. It will of course help them if they have seen both high and low grade examples previously.
