The Pryce character in Better Call Saul was pretty funny. They got some things right ("It's a mint, 60/40, 90/10 on the reverse. I could go on...") but sadly couldn't follow it up. When Mike works it out with Nacho to get his cards back, they bring out a bunch of junk wax boxes that supposedly contain this guy's Mantle and Aaron cards. If they were worth the fortune he had told the police, you would expect to see slabs - but he's digging through raw commons and then claims to find all the expensive cards. Not super believable.
It's hard to get hobby details right for stuff like this. Even Stephen King screwed it up in "Needful Things." It was clear he had done some card research, but some of the things he said just came across as a bit off, referring to "Fleers" and "Lucky Strike" cards.
