The 1988 Score Ron Guidry #310 is a Baseball card released in 1988. Ungraded copies carry a market value of about $1.30.
An ungraded copy is worth around $1.30, a PSA 10 (Gem Mint) around $31.99 and a pristine BGS 10 around $42.00. That's roughly a 25× 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 ($1.30) and top-graded ($31.99) 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.
