Frequently asked questions

Is it worth grading Professor Oak's Research Expedition Base Set 149/165?

A PSA 10 currently sells for about £268.87, raw the card sits at £16.72 — 16,1× as much. Mathematically, submitting returns £268.87 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.

What will I get for Professor Oak's Research Expedition Base Set 149/165 if I want to sell quickly?

Half of all sales fell between £7.90 and £12.81, with a median of £9.96. Selling fast lands you nearer the lower end; with patience, good photos and a complete title the upper end is achievable.

Below which price is an offer for Professor Oak's Research Expedition Base Set 149/165 unrealistic?

The cheapest genuine sales were around £5.63. Offers well below £3.38 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.
