Is it worth grading Professor Oak Base Set 88/102?
A PSA 10 currently sells for about £2,610, raw the card sits at £36.38 — 71,7× as much. Mathematically, submitting returns £2,610 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 Base Set 88/102 if I want to sell quickly?
Half of all sales fell between £21.17 and £33.55, with a median of £26.89. 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 Base Set 88/102 unrealistic?
The cheapest genuine sales were around £6.51. Offers well below £3.90 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.
