@HoloAndBroke asks
one card's number suddenly looks ridiculous and makes my total jump. How do I treat that?
Jeff answers
I'd check that exact entry in our app, verify the version, and look for supporting comparable sales before relying on it. Keep the unusual figure flagged as uncertain in your own notes. One questionable reference shouldn't quietly become the basis for valuing the entire collection.
