I have no problem with questioning or even attacking the TPGs. I stay out of these arguments simply because I do not "get" the whole principle of locking coins away in plastic coffins. For me the joy of "collecting" is finding coins - often in unexpected places and at low prices - to add to my collection, regardless of grade. When I can, I improve the grade of the coins I have and move on the redundant ones. The thrill is in the hunt and filling the gaps.
Graded and encapsulated coins seem to me much more of an investment or commodity based game, which is alien to me. Hence I do not give a fig for the debates back and forth on which TPGs grade how and which system is right or wrong. If I like a coin and I can afford it, I buy it. If it happens to be in a plastic coffin, I will break it out - unless it is so valuable it makes more sense to sell it on as it is.
Watch me get flamed for stating my opinion - another reason why I usually stay out of these debates.And @ozjohn please don't leave - this forum moves pretty slowly, so the lack of opinion from others is more to do with the number of people watching.
