The 2017 SM Black Star Promos Mewtwo & Mew-GX #SM191 is a Pokémon card released in 2017. Ungraded copies carry a market value of about $349.82.
An ungraded copy is worth around $349.82, a PSA 10 (Gem Mint) around $3 and500.00. That's roughly a 10× 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 $349.82 and top grades reaching $3,500.00, 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.
