The 2021 Topps Base Set Frank Thomas SP #520 is a Baseball card (SP parallel) released in 2021. Ungraded copies carry a market value of about $5.59.
An ungraded copy is worth around $5.59, a PSA 9 around $16.09, a PSA 10 (Gem Mint) around $35.64 and a pristine BGS 10 around $46.00. 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 ($5.59) and top-graded ($35.64) 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.
