Since 1996, Major League Baseball's prestigious “500 Home Run” club has doubled in size from 14 members to 28. Even with this considerable growth spurt, this exalted slugger club is still extremely exclusive given the vast number of ballplayers who have swung a bat over the years. Rounded up are (12) 500 Home Rub Club member single-signed baseballs, representing 43% of the club’s total population. All are official league balls ranging (EX to NM) and 75% have pertinent inscriptions. In addition to ranking among the game’s all-time greatest sluggers, four of these legends are also members of the equally exclusive “3,000 Hit Club” (Willie Mays, Hank Aaron, Eddie Murray, and Albert Pujols). Signature strength ranges ("7” to “9”) unless noted, with:
