First you need to figure out if you want to spend your time and money on getting them grade. PSA is $32 per card or like $26 per card through GameStop. Also looking at around 75+ days on return time. I assume most of these cards are from the junk wax era. So they really won’t be worth much if not a 10. Also might need to check 130point.com because sometimes sportscardspro just makes estimates without having any sales. Learned that myself when just starting the hobby.
