The 2026 Topps Finest Mega Autograph Ben Williamson Mini-Diamond Refractor #FMA-BW is a Baseball card (Mini-Diamond Refractor parallel) released in 2026. Ungraded copies carry a market value of about $3.00.
An ungraded copy is worth around $3.00, a PSA 9 around $14.74, a PSA 10 (Gem Mint) around $43.78 and a pristine BGS 10 around $57.00. That's roughly a 15× 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 ($3.00) and top-graded ($43.78) 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.
