Is it worth grading Professor Oak's Research Expedition Base Set 149/165?
A PSA 10 currently sells for about $354.93, raw the card sits at $22.07 — 16,1× as much. Mathematically, submitting returns $354.93 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 $10.43 and $16.92, with a median of $13.14. 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 $7.43. Offers well below $4.46 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.
