1992 Sports Illustrated for Kids Rookie Card of legendary U.S. Soccer superstar Mia Hamm AUTOGRAPHED in blue Sharpie with her old mid 1990s signature and graded 9 (MINT) by Beckett Grading Services (BGS). The autograph is graded a perfect 10/10. An unsigned PSA 10 specimen of this card sold for $34,440 in June 2021.

This card is MUCH rarer, a UNIQUE 1/1 card, as Mia stopped signing like this around the time of the 1996 Atlanta Olympics. This autograph was obtained in person just months earlier (January 1996). While a PSA 10 graded card is rare, there potentially are dozens of other cards in existence that could earn the same grade. However, you would need a time machine to get this card signed with her old mid 1990s signature!
