$20 Pete Rose, in the early 1990's, auto on a ball I bought separately. Interestingly, in 1986 I got an autograph on a ball I supplied from Bob Feller at a card shop official signing. He charged $2. Always liked that guy for that reason. My wife bought me a Stan Musial signed ball in Cooperstown after he passed, because I could never get his autograph over the years he was in Cooperstown for the HOF ceremonies. Not sure what she paid but the Coopstown, NY storefronts aren't cheap.
