I found the below thread that MIGHT help. Apparently there was some sort of a software glitch or something at some point or another causing all of the older label BVG cards to be lost into the void. With their current backlog in grading might not be worth it now but down the road it might be worth reaching out to them and they can reslab with a categorized serial number or something.
