The 2026 Topps Series 2 Kyle Harrison Yellow Rainbow Foil #670 is a Baseball card (Yellow Rainbow Foil parallel) released in 2026. Ungraded copies carry a market value of about $5.20.
An ungraded copy is worth around $5.20, a PSA 9 around $18.21, a PSA 10 (Gem Mint) around $53.65 and a pristine BGS 10 around $70.00. That's roughly a 10× 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 ($5.20) and top-graded ($53.65) 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.
