Is it worth grading Impostor Professor Oak Base Set 73/102?
A PSA 10 currently sells for about £127.08, raw the card sits at £50.43 — 2,5× as much. Mathematically, submitting returns £127.08 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.
Auction or Buy It Now — which gets more for Impostor Professor Oak Base Set 73/102?
Across 8 auctions the median was £39.62, across 14 fixed-price sales £33.46. Auctions therefore fetched about 18 % more — worth it mainly for sought-after cards with several bidders.
What will I get for Impostor Professor Oak Base Set 73/102 if I want to sell quickly?
Half of all sales fell between £13.31 and £53.16, with a median of £23.72. 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 Impostor Professor Oak Base Set 73/102 unrealistic?
The cheapest genuine sales were around £7.20. Offers well below £4.32 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.
