One of my hobbies is to mail cards to baseball players and request and autograph. I mail their card (prefer to use the least glossy card possible), a SASE and a note of thanks for taking the time to sign my card. I usually send between 50 and 100 cards a season and get ~20% back. I have gotten some great returns (whether they are real or autopen, I dont know, but they all look great and are on the card I sent)- Derek Jeter, Joey Votto, CC Sabathia, Roy Halladay, Jorge Posada, Roberto Alomar, Curtis Granderson, Mike Mussina, John Smoltz, Mark Texiera and Ryan Zimmerman. In one two day period I got cards returned & signed by Cliff Lee, Joey Votto, Jorge Posada and David Wright:
