My concern is that the focus might (or probably has in some quarters) shift from the coin to the grade. So instead of people looking for a nicer coin, they seek a higher number.This to me is the inherent problem with all TPGS. Whether one is better or not is to me, a moot point. Protection of coins, conservation, authentication? I have no problems with any of those.But fuelling the 'number chasing' craze? They are all bad in that respect to my eyes and as Rob alludes, people need to learn to make up their own minds about a coin, instead of relying on someone else. IMHO..I totally agree that chasing the number is a problem. everyone should learn to grade and judge each coin on it's own merits. I also agree that registry sets tend to attract buyers of the number and not the coin. My argument is for those who are unsure of their grading skills and enjoy the hobby by collecting already graded coins - a universal grading system would be beneficial - as long as consistency in grading applies.
