Sadly, yes. A field experiment involving baseball card auctions on eBay:
Photographs showed the cards held by either a dark-skinned/African-American hand or a light-skinned/Caucasian hand.
Cards held by African-American sellers sold for approximately 20% ($0.90) less than cards held by Caucasian sellers, and the race effect was more pronounced in sales of minority player cards.
