"A card of a rookie you thought you were 'investing' in." I never really collected cards thinking I would sell them, so this doesn't particularly apply to me. However, as a kid I did keep some of my better duplicate cards in plastic, thinking I might sell them or trade for something good, so I should keep them in good condition. I don't remember all of the cards (none of them were particularly good by modern standards) - pretty sure one was the Juan Gonzalez Topps rookie.
