Presented is a 500 Home Run Club multi-signed, limited-edition (51/300) bat with the signatures (averaging 7 or 8/10) of eleven (11) 500 Club members: Mantle, Williams, Mays, Aaron, F. Robinson, Schmidt, R. Jackson, Killebrew, McCovey, Banks, and Mathews. The Rawlings Adirondack P302 bat has a length of 34" and a weight of 29.4 ounces, and a metallic 2.25x3" plaque, reading "500 HOME RUN CLUB", fastened onto the barrel with the machine-stamped names of the eleven signers. The signatures were written in blue fine tip marker, and Mantle added an inscription of "536" for his homer total, and an unknown hand has written "51/300 BH" in blue fine tip marker on the knob. The unused bat is in excellent condition.
