Mewtwo & Mew GX

A PSA 10 currently sells for about $1,880, raw the card sits at $415.84 — 4,5× as much. Of 20.191 copies already graded, 50 % received a 10 and 35 % a 9. Mathematically, submitting returns $1,225 on average, before fees and shipping. Rule of thumb: submit when the value at a realistic grade is at least double the raw value — which is the case here. Centering decides it: an off-centre card will not get a 10. The grade distribution comes from the PSA Population Report; people pre-sort before submitting, so your own hit rate may differ.

Across 179 auctions the median was $475.55, across 438 fixed-price sales $404.89. Auctions therefore fetched about 17 % more — worth it mainly for sought-after cards with several bidders.

Half of all sales fell between $198.35 and $385.37, with a median of $291.70. Selling fast lands you nearer the lower end; with patience, good photos and a complete title the upper end is achievable.

The cheapest genuine sales were around $138.55. Offers well below $83.13 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.

lastsold uses only real sales — eBay plus auction houses like Goldin & Fanatics — recent sales count more (recency weighting), outliers and fakes are removed. It's not an estimate but actual sold prices, separated by condition, language and grading.
