The 1984 Fleer Parrish & Boone Backstop Stars #637 is a Baseball card (Backstop Stars parallel) released in 1984. Ungraded copies carry a market value of about $1.39.
An ungraded copy is worth around $1.39, a PSA 9 around $6.00, a PSA 10 (Gem Mint) around $21.78 and a pristine BGS 10 around $28.00. 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 ($1.39) and top-graded ($21.78) 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.
