Previous research finds that customer racial discrimination decreases the price of a non-white baseball player’s card but does not decrease the price of a non-white basketball player’s card. This paper seeks to examine if racial minority or league minority affects the value of a trading card. Using disaggregated player performance data from 1977 we explore this question with baseball cards (in which non-white players are the league minority) and basketball cards (in which white non-players are the league majority). Using Tobit regressions, we find that customer discrimination exists against non-white players in both baseball and basketball leagues.
