The 1990 Score Brian Harper #189 is a Baseball card released in 1990. Ungraded copies carry a market value of about $1.10.
An ungraded copy is worth around $1.10, a PSA 10 (Gem Mint) around $24.39 and a pristine BGS 10 around $32.00. That's roughly a 22× 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 ($1.10) and top-graded ($24.39) 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.
