@JustHereForPikachu asks
there's a handwritten note about who gave me a card. Should I throw those out when I clean up?
Jeff answers
I'd save it. Keep the note outside direct contact with the card, or photograph it and file it with your collection records. Identification tells you what a card is; little notes tell you why you kept it. Those are different kinds of useful information.
