The 1999 Stadium Club Triumvirate Frank Thomas Luminous #T15A is a Baseball card (Luminous parallel) released in 1999. Ungraded copies carry a market value of about $18.00.
An ungraded copy is worth around $18.00, a PSA 9 around $29.00, a PSA 10 (Gem Mint) around $54.50 and a pristine BGS 10 around $71.00. That's roughly a 3.0× 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 ($18.00) and top-graded ($54.50) 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.
