The 2018 Panini Obsidian Matrix Autographs Michael Porter Jr. Green #MA-MPJ is a Basketball card (Green parallel) released in 2018. Ungraded copies carry a market value of about $51.62.
An ungraded copy is worth around $51.62, a PSA 9 around $95.52, a PSA 10 (Gem Mint) around $108.52 and a pristine BGS 10 around $141.00. The gem-mint premium is modest (about 2.1× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $51.62 and top grades reaching $108.52, 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.
