[the cardboard fan]

^ They list the 1st licensed card from a baseball card manufacturer as a RC with the older stuff and since the rules changed in 06 it is the players card from their rookie season unless they previously had a RC from 05 or older and in that case the rookie year card is labeled as (RC) which I personally call Second Year Rookie Cards due to a lack of a better term

Seems realistic enough to me but I get where you're coming from on that
