Why this card matters
pop
6,480 total PSA submissions is meaningful supply. PSA 10s at 302 (4.7% gem rate) create real scarcity at the top, but 1,821 PSA 9s dilute mid-tier conviction.
demand
Mewtwo is an A-tier IP anchor with perennial collector pull. Armored variant adds alt-form premium. Character demand is structural, not trend-dependent.
artist
Full-art holo treatment on Armored Mewtwo is visually distinctive. SM promo finish is clean and era-definitive, though not a landmark illustration credit.
catalyst
16.7% 30d momentum is notable but rests on thin PSA 10 comp volume (single $9,472 sale). SGC/CGC 10 divergence ($3K/$787) signals grader arbitrage, not broad market confirmation.
