The 2026 Topps Series 2 Blas Castano Blue Rainbow Foil #688 is a Baseball card (Blue Rainbow Foil parallel) released in 2026. Ungraded copies carry a market value of about $1.99.
An ungraded copy is worth around $1.99, a PSA 9 around $13.12, a PSA 10 (Gem Mint) around $38.99 and a pristine BGS 10 around $51.00. That's roughly a 20× 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 ($1.99) and top-graded ($38.99) 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.
