The 2026 Topps Flagship Seth McGowan Diamante #388 is a Football card (Diamante parallel) released in 2026. Ungraded copies carry a market value of about $1.11.
An ungraded copy is worth around $1.11, a PSA 9 around $11.78, a PSA 10 (Gem Mint) around $35.24 and a pristine BGS 10 around $46.00. That's roughly a 32× 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 ($1.11) and top-graded ($35.24) 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.
