Condition & Value Assessment
Condition Grade
Very Good (VG 3)
Estimated Market Value
Raw: $0.10 - $0.25 | Graded PSA 10: $15 - $25 (extremely low volume)
Recent Sales
Bulk lots of 1991 Pro Set commons typically sell for pennies per card. Individual sales are rare due to high production volume, with most transactions occurring in team set bundles for $1-$3.
Condition Details
Extensive whitening on all four corners; significant chipping and edge wear along the top green border; bottom-left corner is heavily soft/dulled; surface shows minor spotting and fingerprint oil from handling; centering is slightly shifted to the left.
Grading Recommendation
Not recommended for grading. The card is a common from the 'Junk Wax' era with high production numbers. The condition of this specific card (VG 3) would result in a grade where the cost of the plastic holder far exceeds the value of the card.
Card Description
Mark Kelso is pictured in his Buffalo Bills home white jersey, number 38. He is shown in an action-running pose on a grass field. The design features a green border with yellow horizontal line accents on the sides, the AFC logo in the top left, and the NFL shield in the top right. Kelso played safety for the Bills and was famous for wearing the 'ProCap' (padded helmet cover) seen in this photo.
Notable Features
Includes the 'ProCap' helmet padding visible on the player's helmet, which was Kelso's signature look to prevent concussions. Features the 'Pro Set - The Official NFL Card' branding at the bottom.
Authentication Notes
Authentic original. The 1991 Pro Set cards have a distinct semi-gloss feel and specific dot-matrix print pattern typical of early 90s mass-production. No signs of counterfeiting as the card has minimal market value.
