1989 · UPPER DECK · #666

This 1989 Upper Deck card commemorates Kirk Gibson's legendary walk-off home run in the 1988 World Series. As part of the first-ever Upper Deck set, it features high production values for its time, but remains common due to the high print volumes of the era. The PSA 8 grade indicates a high-quality card, though the market value is largely tied to the historical significance of the image.
