Al C.risafulliBarry, I touched on this above - I agree with you. There's no way to get grading companies to agree on grading standards, any more than we can get two collectors in a room and have them agree on whether a card is "VG" or "G-VG".
The agreement needs to be on business practice. What kind of tools/training do they give their graders, what kind of experience is required, what reference materials do they use, what kind of environment do they grade cards in? What's the QC procedure, how are the cards slabbed, how do they respond to customer inquiries or problems, what kind of guarantee do they have in place. And, most importantly, what do they do when a customer issue arises.
The subtle differences in grading standards are one of the things that give both of the reputable grading companies in this hobby their niche. Tough to establish a standard that makes them both the same would be a difficult thing to get them to agree to.
