I have listed many vintage and rare single signed baseballs on ebay, under username tonyiii.
Some of them include: Rabbit Maranville, Lou Gehrig, Paul Waner, Babe Ruth, George Kelly, Lefty Grove, Gabby Hartnett, Waite Hoyt, Stan Coveleski, Red Ruffing, Sam Rice, Jackie Robinson and Travis Jackson.
If you are interested in buying them directly, I would pass on the ebay and paypal savings.
