Mewtwo & Mew GX #SM191 — collector's take

Is Mewtwo & Mew GX #SM191 worth grading?

So is it worth grading? Here is the honest math: a raw copy sits at $275, a Grade 9 comes in at $448, and a true PSA 10 jumps all the way to $1,719, which works out to 6.3 times the raw price. That is a real jump, no question, but gem mint is called gem mint for a reason. Corners, centering, and surface all have to cooperate, and grading fees plus shipping and turnaround time eat into your margin if the card comes back a 9 instead of a 10. If your copy already looks clean under a light, it is worth considering. If it has soft corners or edge wear, you might be paying to confirm what you already suspected.

How rare is it?

We do not have official population figures to lean on here, but the price gap between raw, Grade 9, and PSA 10 tells its own story. When a PSA 10 sells for 6.3 times the raw copy, that usually means gem mint copies are the exception, not the rule, especially for a promo card that already sees plenty of handling before it ever reaches a grader. Scarcity at the top end is exactly what pushes that PSA 10 number up near $1,719 while the raw market stays comparatively grounded.

Where to pull it

This is where PackSpy's own data actually helps, because we track real pulls across sites like collector-crypt, courtyard, mnstr, packs, and tilt-rips, and Mewtwo & Mew GX #SM191 has shown up 200 or more times across those platforms. That is not a guess, that is recorded pulls. We have seen it surface in packs like the Elite Pokemon Gacha Pack, Pokemon Pro Pack, Grail Pokemon Gacha Pack, Starter Pokemon Gacha Pack, and Pack 1, and the biggest single pull we have on record hit $3,500. Worth remembering though, opening packs is still a gamble, and most rips do not come close to that number, so chase the fun of it, not the guarantee.

Questions people ask

How much is Mewtwo & Mew GX #SM191 worth?

A raw or ungraded copy is valued at $275 right now. Grade it and get a 9 and you are looking at $448, while a PSA 10 gem mint copy reaches $1,719. The gap really shows how much condition matters for this card.

Is Mewtwo & Mew GX #SM191 worth grading?

It can be, since a PSA 10 sells for 6.3 times the raw price. Just go in with your eyes open, gem mint copies are hard to land, and grading fees and turnaround time are a real cost if it comes back lower than hoped.

What set is Mewtwo & Mew GX #SM191 from?

It is from the Promo set, which is part of why it carries its own kind of appeal, a standalone card outside the usual expansion structure. That promo status is part of what keeps collectors hunting for it.
