The 1990 Topps Boomer Studies the Defense #502 is a Football card released in 1990. Ungraded copies carry a market value of about $1.49.
An ungraded copy is worth around $1.49, a PSA 10 (Gem Mint) around $24.95 and a pristine BGS 10 around $32.00. That's roughly a 17× 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 ($1.49) and top-graded ($24.95) 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.
