Mewtwo GX from Shining Legends delivers a 1329% ROI, crushing every modern Mewtwo printing and proving that vintage psychic-types still own the grading market. At $599 raw, it grades to $8,922 PSA 10 with a 16.7% gem rate, netting $8,298 profit per card. That's not nostalgia—that's math.
When the same Pokémon prints across multiple sets and eras, the spread in grading value tells you exactly which version to buy. Mewtwo is the perfect case study: it shows up in 76 different cards across our database, but only eight printings matter for flipping. The data reveals a brutal hierarchy: vintage and promo cards dominate, while recent main-set releases barely move the needle.
The Mewtwo Hierarchy: Vintage Crushes Modern
Shining Legends Mewtwo GX is the undisputed champion. A 16.7% gem rate might look modest, but the PSA 10 comp is $8,922—so high that even a modest 1-in-6 shot at a 10 still nets over $8,000 per card. Compare that to Team Rocket's Mewtwo ex from Ascended Heroes, which hit market earlier this year and trades at $357 raw, $715 PSA 10, and 69.4% gem rate. The math: higher gem rate, lower absolute profit. You're hitting a 10 more often, but each one is worth 92% less.
This is the core of cross-set flipping: gem rate and absolute PSA 10 price move in opposite directions. Raw supply matters. Shining Legends (2021) is scarcer than Ascended Heroes (2026). Scarcity drives PSA 10 comps. Higher comps justify the risk of a lower gem rate. Newer sets printed more copies; more copies in collector hands means fewer reach PSA 10, and fewer reaching PSA 10 means weaker markets on the back end.
Mewtwo & Mew GX from Shining Legends Promo (#SM191) sits second, with 1055% ROI on a 53% gem rate and $3,396 PSA 10. It's easier to grade, but the profit ceiling is lower. That's the trade-off flippers face: do you want high frequency low-value hits, or rare high-value hits? For capital efficiency, you want rare high-value hits. For volume and certainty, you want frequency. Shining Legends GX targets pure profit per card.
Moving to modern printings, the drop is steep. Team Rocket's Mewtwo ex from Destined Rivals (released earlier in 2026) shows 118% ROI—roughly 11× lower than Shining Legends GX. Raw price is $492, PSA 10 is $1,127, and gem rate is 56%. This card is selling (1,938 times per year), but the money is thin. Even a hit rate above 50% can't overcome a PSA 10 comp that's 87% lower.
Japanese printings add texture. Mewtwo & Mew GX from Tag All Stars (#222) delivers 252% ROI at a 76% gem rate—the highest gem rate in the set. Only 148 sales per year, but when they hit, $1,208 PSA 10 comp justifies the $318 raw buy. That's a playable middle ground: not Shining Legends money, but real ROI on decent volume.

Why Vintage Mewtwo Wins
Shining Legends released in May 2021 and is closed. No more copies are entering circulation. By contrast, Ascended Heroes and Destined Rivals are fresh, and Mega Dream EX (2015) is in the long tail of supply erosion but never had Shining Legends' print run.
The market also recognizes Mewtwo's lore. Base Set Mewtwo (10/102) isn't in this sample—it's a rarer beast priced far above our dataset—but Shining Legends Mewtwo GX captured the modern promo of that same legend. When a card channels iconic Pokémon through a recent lens, it holds value better than a generic ex or GX in a commodity set.
Market volume supports this. Shining Legends GX has 1,330 sales per year at the PSA 10 level. Ascended Heroes Mewtwo ex (released January 2026) has 2,559 sales per year but at 87% ROI. Higher volume doesn't redeem low per-unit profit. You want volume and high ROI—and that only happens when raw supply is controlled and PSA 10 comp is strong.
The Play Right Now
If you're building a stack to grade, Shining Legends Mewtwo GX is the target. At $599 raw, you're betting on a 1-in-6 shot at $8,922. That single hit covers 14 whiffs. The math is lopsided in your favor. Even with 16.7% gem rate, EV is $1,885—nearly $1,900 in expected value per card before fees.
Japanese Tag All Stars Mewtwo & Mew GX is the secondary play if Shining Legends stock is tight. 76% gem rate means you're hitting more often; each hit at $1,208 PSA 10 still prints $865 net. You trade ceiling for certainty.
Avoid modern main sets. Destined Rivals and Ascended Heroes are liquid (high volume), but the per-card return is meal money. Unless you're moving volume across a warehouse, the ROI spread doesn't justify storage and logistics.

How we calculate this
EV (expected value) = sum over all possible grades of: P(grade) × PSA 10 price × (1 − seller fee) − raw cost − grading fee. Gem rate is the percentage of copies graded that came back PSA 10, sourced from live PSA population data. Net profit = EV − raw cost. ROI = (net profit ÷ raw cost) × 100.
