Sotheby's used to do regular sports auctions, as part of their collectables department, but they quit a few years ago.

Old baseball does not have the widespread appeal of, say, a Marilyn Monroe auction, so I wouldn't expect that Christies does it to effect he prices much if at all.

If you see Sotheby's and Christies other auctions and total sales, you will see that a Mastro or REA auction is small potatoes for them.
