Collection of thirteen different single-signed baseballs, including eleven signed by a Hall of Fame player. Three of the balls, duly noted in our listing, come with COAs from PSA (COA hologram label affixed to the ball). Unless otherwise noted the signatures, scripted in a variety of inks, grade between 7/10 and 10/10 and appear on the sweet spot of either an Official American or National League ball (1980s era). The players represented here are Hank Aaron (PSA COA), Willie Mays (PSA COA), Don Drysdale (PSA COA), Billy Herman, Bob Feller, Duke Snider, Warren Spahn, Brooks Robinson, Whitey Ford, Ralph Kiner, Yogi Berra, Don Mattingly (signature grades 5/10), and Jesse Barfield (signed on a side panel). All the balls display varying degrees of age toning, and a few also exhibit some minor blemishes. Very Good to Excellent condition overall.
