The 1993 Topps Base Set Mike Harkey Marlins Inaugural #657 is a Baseball card (Marlins Inaugural parallel) released in 1993. Ungraded copies carry a market value of about $3.42.
An ungraded copy is worth around $3.42, a PSA 10 (Gem Mint) around $22.00 and a pristine BGS 10 around $29.00. That's roughly a 6.4× 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 ($3.42) and top-graded ($22.00) 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.
