JP: Promo · 150
A raw Mewtwo [Game Boy] from JP: Promo currently sells for about $601.46. Across 19 completed eBay sales, a PSA 10 has a median price of $5601.00. After a $25 grading fee, a 10 would net roughly $4974.54. But a Grade 9 (mixed graders) has a median of $1435.00 across 20 sales — which works out to +$808.54 after fees. Even a 9 profits at current prices. 9s are pooled across graders here — PriceCharting has no PSA-9-only figure.

Knowing a card is worth grading is the easy half. PokeSnipez watches eBay around the clock and flags raw copies of this card closing below market — so you can actually make the trade, not just read about it.
See live grade snipes →Every figure on this page is an observed number. Raw prices come from TCGplayer; graded medians are completed eBay sales, shown with the sale count behind each one. We don't estimate, model, or fill in gaps — if a grade has no sales on record, it isn't listed. Grading outcomes are not guaranteed: most raw cards do not come back a 10, which is exactly why the 9-grade number is on this page. Where PriceCharting has no PSA-9-only figure we show its pooled 9 — PSA, BGS, CGC and SGC together — and label it as such rather than call it a PSA 9.
