@ReprintRookie asks
if two different companies both give a card a 10, are those basically interchangeable?
Jeff answers
I wouldn't assume that. Companies have their own standards, labels, and reputations, and buyers don't necessarily pay the same for each. For a price check, I start with the exact card in our app and then compare sales from the same grading company and grade. For your own collection, also consider which holder and presentation you actually like.
