I bought a vintage baseball from him couple months back(did not know he has sold so many questionable items). But I was surprised he barely did research on the ball I bought. It was being sold as a 1920's vintage signed ball with Nick Altrock and others. He clearly missed a Walter Johnson autograph on the side panel. And under a black light it showed autos of Honus Wagner, John J McGraw and other hofers. Turned out to be a 1925 World Series ball.
