Acquired from New York Yankees ex-bullpen coach Nick Testa, this assortment in excess of 425 baseballs must be seen to be believed. There are 30+ team balls, five (5) with Derek Jeter. Other highlights include: five (5) Mickey Mantle & Whitey Ford dual-signed balls, three (3) Old Timers signed balls w/Mickey Mantle. Some Yankees include: Derek Jeter (4), Ichiro (2), Mariano Rivera (7), Alex Rodriguez (5), Yogi Berra (18), Jorge Posada (11), Hideki Matsui (15), Jim "Catfish" Hunter, Randy Johnson, Bobby Murcer, Joe Torre, Whitey Ford, Don Mattingly, Reggie Jackson (10+), Andy Pettitte, Bernie Williams, Ron Guidry, Sparky Lyle, Don Larsen, Paul O'Neill, Dave Winfield, Phil Rizzuto and many more. Other non-Yankees include: Richard Nixon, Kirby Puckett, Willie Mays, Nolan Ryan, George Brett, Bo Jackson, Ernie Banks, Cal Ripken Jr, David Ortiz, Larry Doby, Spike Lee, Eddie Murray, Ozzie Smith, and Bob Murphy. An interesting signed baseball from Trevor Hoffman to Mariano Rivera is inscribed, "Mariano - The way you go about your business, you are admired from afar," a significant statement from a top-line peer. Signed baseball from Jorge Posada to Derek Jeter inscribed, "To Derek, Happy B-Day Dick." Many are inscribed to Nick and there are duplicates, but less than a quarter show toning/spotting, and some signatures show light smudging - a Pinstripe potpourri.
