Collection: John Mackey Signed Memorabilia

John Mackey was a tight end for the Baltimore Colts, remembered as one of the players who redefined the position with his combination of size and speed. Collectors seek out his autograph as a link to that era of NFL football and to the Colts teams he anchored.

This collection includes signed 8x10 photos of Mackey in his Indianapolis Colts imagery, available both framed and unframed, along with a signed cut autograph. Authentication comes from Beckett, PSA, and JSA depending on the item, so buyers should check which certifying body backs each piece and confirm the COA number matches the paperwork included.
