The 1988 Topps Mark Kelso #231 is a Football card released in 1988. Ungraded copies carry a market value of about $1.36.
An ungraded copy is worth around $1.36, a PSA 9 around $22.00, a PSA 10 (Gem Mint) around $32.10 and a pristine BGS 10 around $42.00. That's roughly a 24× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.
Is it worth grading?
The spread between raw ($1.36) and top-graded ($32.10) copies is fairly tight, so grading this card only makes financial sense for truly flawless copies — or for collectors who simply prefer slabbed cards for protection and display.
