The 2018 Bowman Mega Box Chrome Autographs Jose Siri Orange Refractor #JS is a Baseball card (Orange Refractor parallel) released in 2018. Ungraded copies carry a market value of about $4.68.
An ungraded copy is worth around $4.68, a PSA 9 around $2.25, a PSA 10 (Gem Mint) around $127.51 and a pristine BGS 10 around $166.00. That's roughly a 27× 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?
With raw copies near $4.68 and top grades reaching $127.51, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
