#XY30Frequently asked questions
Is it worth grading Blastoise V SWSH Black Star Promos SWSH101/307?
A PSA 10 currently sells for about £156.19, raw the card sits at £6.16 — 25.3× as much. Of 605 copies already graded, 50 % received a 10 and 37 % a 9. Mathematically, submitting returns £101.58 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 Last Sold determine the market value?
Last Sold 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.
