Why rainbow Mewtwo and Mew leads
Mewtwo and Mew GX rainbow secret 242/236 is Unified Minds' most expensive card. The TCGplayer Seller Blog reported a $332.86 market price after a steady climb since June in its December 9, 2025 update in the TCGplayer price trends report.
The same card lists near $376 raw while PSA 10 copies are valued around $650 to $800, according to Eneba in the Eneba Sun and Moon value guide. That gap leaves room for profit on truly clean copies.
Which alternate arts also justify grading
Mega Sableye and Tyranitar GX alternate art 226 sits near $328. Eneba ranks it with Raichu and Alolan Raichu GX and Slowpoke and Psyduck GX alternate arts as the set's other top grading targets.
MoneyMade documents Full Art Mewtwo and Mew GX 242 trading from $60 to $400 with a highest sale of $1,925. That range shows high-grade examples capture outsized returns for collectors and sellers.
Why regular ultras fall short
TheGamer's March 2025 ranking places regular Full Art Mewtwo and Mew GX near the bottom of the set's top 10 at about $53.89. That lower base leaves little room to cover fees after grading.
Collectors chasing resale should save submissions for secrets and alternate arts. Keep clean regular ultras raw or for personal sets.
What grading costs and how long it takes
Pokemon Price Tracker reports PSA holds over 70 percent of graded Pokemon share. It lists about $18.99 to $21.99 bulk and $27.99 individual with 60 to 120 day economy turnaround in its January 24, 2026 guide in the Pokemon Price Tracker grading guide.
A $53 card cannot absorb that fee and wait. A $300-plus secret can, if it earns a top grade.
How to screen a card before submission
Pokemon Price Tracker notes PSA 10 needs 55/45 or better front centering and 75/25 back with flawless corners, edges and surface. Use that standard as a hard filter at home.
Pokemon Price Tracker adds PSA 10 can bring 5 to 10 times raw while lower grades add little. Submit only pack-fresh, well-centered chase cards.
- Compare front borders top to bottom and left to right.
- Flip and check back borders and corners.
- Tilt under light for scratches, dents, and edge wear.
