The 2020-21 Donruss Optic Base Set Michael Porter Jr. Purple #75 is a Basketball card (Purple parallel) released in 2021. Ungraded copies carry a market value of about $1.38.
An ungraded copy is worth around $1.38, a PSA 10 (Gem Mint) around $62.00 and a pristine BGS 10 around $81.00. That's roughly a 45× 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 $1.38 and top grades reaching $62.00, 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.
