What if another party, who isn't the noted group, had a better opinion of you than that?
But what about the comic art community, which is the group that is being addressed here? I'm going to assume most of us here are not in the category of "family and patients" so that doesn't do us any good in lending credibility to Ankur's statements or bolstering his reputation. Reputation in any collecting community is key.
Age old knowledge, you know who you're buying from, otherwise you are assuming risk. CAF has no involvement in that risk as it's between seller and buyer. And no, despite subjectivity to grading, comic books don't increase a grade or two when you go to sell them, even if they've been kept in some magical restorative safe deposit box
