AI Appraisal Estimate

This is a 1990 Pro Set football card featuring wide receiver Tim Brown during his college career at Notre Dame, part of the 'Heisman Hero' subset. The card measures approximately 2.5 by 3.5 inches and is constructed from standard medium-weight cardstock with a semi-gloss finish. The front features a full-bleed action photograph of Brown in a dark blue and gold Notre Dame jersey with the number 81. Notable markings include the 'NFL Pro Set' official logo in the top left and a gold/green banner at the bottom identifying him as the 1987 Heisman Hero. The card is currently housed in a clear plastic soft sleeve. Significant condition issues are present: there is heavy black ink handwriting across the top white margin that reads 'COPYWRIGHT ERROR' in a non-professional hand. While 1990 Pro Set is known for numerous printing variations, this specific ink marking is aftermarket graffiti rather than a factory error, which severely impacts the card's collectible value and grading potential. The edges show slight silvering and soft corners, typical for mass-produced cards of the early 1990s 'junk wax' era.

I have examined the 1990 Pro Set Tim Brown #36 'Heisman Hero' trading card based on the visual information provided. This item represents the 'junk wax' era of the early 1990s, characterized by massive production volumes that have kept market values for most base and subset cards extremely low. In 'Near Mint' condition, this card typically retails for less than one dollar. The card's condition is significantly compromised. My examination reveals soft corners and edge silvering, but the most detrimental factor is the 'COPYWRIGHT ERROR' ink inscription across the top margin. While the 1990 Pro Set is famous for legitimate printing variations (such as the Ludlow or partial-stat errors), this marking is clearly aftermarket graffiti. In the sports card market, such defacement renders the card 'Poor' or 'Authentic Altered' by third-party graders, effectively removing its collectible appeal to serious numismatists or investors. From a visual audit, the cardstock and printing appear consistent with 1990 Pro Set standards, but definitive verification of authenticity is limited by the digital format. A physical inspection would be required to verify stock thickness, surface gloss, and to confirm the ink is indeed post-factory. No scientific testing is typically warranted for a low-value card of this era, as the cost of authentication would exceed the value of the asset many times over. The current market demand for defaced mass-produced cards from this period is non-existent, and the value is nominal/sentimental only.
