The 2024-25 Topps Chrome Instinct Stephon Castle Purple Geometric Refractor #INS-28 is a Basketball card (Purple Geometric Refractor parallel) released in 2025. Ungraded copies carry a market value of about $8.34.
An ungraded copy is worth around $8.34, a PSA 9 around $22.08, a PSA 10 (Gem Mint) around $61.20 and a pristine BGS 10 around $80.00. That's roughly a 7.3× 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 $8.34 and top grades reaching $61.20, 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.
