1988 Topps Big Keith Hernandez #59 value & prices

The 1988 Topps Big Keith Hernandez #59 is a Baseball card released in 1988. Ungraded copies carry a market value of about $1.74.

An ungraded copy is worth around $1.74, a PSA 10 (Gem Mint) around $27.37 and a pristine BGS 10 around $36.00. That's roughly a 16× 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 ($1.74) and top-graded ($27.37) 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.
