Frequently asked questions

Is it worth grading Professor's Research Prismatic Evolutions 123/131?

A PSA 10 currently sells for about £148.31, raw the card sits at £1.32 — 112,5× as much. Mathematically, submitting returns £148.31 on average, before fees and shipping.

Below which price is an offer for Professor's Research Prismatic Evolutions 123/131 unrealistic?

The cheapest genuine sales were around £0.73. Offers well below £0.44 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.

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.
