Is it worth grading Mewtwo V SWSH Black Star Promos SWSH229/307?
A PSA 10 currently sells for about £98.84, raw the card sits at £5.99 — 16,5× as much. Of 7.815 copies already graded, 51 % received a 10 and 35 % a 9. Mathematically, submitting returns £62.84 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.

How does lastsold determine the market value?
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.
