I know I can find duplicates now by going to: Items > Find > "Qty In Stock" > "is greater than" > "1" and it will identify the multiple copies (2+) of comics of the same issue and the same grade. There in lies the problem as for example I have an Amazing Spider-Man #194 in CGC 9.6, CG 9.0 and an ungraded copy and to me, I have two duplicates of issue #194 that I may wish to sell and just keep the highest graded copy. It would be very handy to identify duplicates of the same comic issue, regardless of the grade. This would be extremely useful for collectors in MHO. Thanks for considering!
