As much as Willie Mays is remembered for his baseball prowess, perhaps lesser known is the Hall of Famer's commitment to helping underprivileged kids. This encapsulated check is signed by Mays and dated July 15, 1995. It is drawn against the "Say Hey Foundation" - which exists to this day - in the substantial amount of $12,855, apparently to cover private school tuition for a student. The autograph in blue ballpoint ink is certified by PSA/DNA.
