@NervousNinetales asks
the binder has price stickers from years ago. Should I use those until I figure everything out?
Jeff answers
I'd keep the stickers as history, not current estimates. Check the exact cards in the infinitepulls.com app; we built it using current market pricing from TCGplayer and Cardmarket for that starting point. Make sure the reference fits the actual version and condition before drawing conclusions.
