You're right. The cheaper cards appear to be newly processed cards, with COMC Item Numbers above 9.2 million.
It looks like this is a new way to do condition notes.
I definitely don't like the fact that they're all appearing on different pages, and appearing without any kind of reference value on the page. One of the biggest advantages of COMC is that every copy for sale of a particular card is right there for you to compare.
As a seller, I rarely sell cards which have no book value. As a buyer, I rarely look at cards without a book value. I do believe that these new reference values are much closer to the actual value of the card than full High Beckett, but I would like to see the reference value, and I would like there to be some way to see every copy of a particular card that is for sale at the same time.
COMC auto accept is currently set at 35% off.
