An ungraded copy is worth around $2.99, a PSA 9 around $13.23, a PSA 10 (Gem Mint) around $16.00 and a pristine BGS 10 around $21.00. That's roughly a 5.4× 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 ($2.99) and top-graded ($16.00) 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.
