Frequently asked questions

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

A PSA 10 currently sells for about €174,41, raw the card sits at €1,48 — 117,8× as much. Mathematically, submitting returns €174,41 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 Professor's Research Prismatic Evolutions 123/131?

Across 6 auctions the median was €0,85, across 25 fixed-price sales €1,56. Fixed price therefore fetched about 84 % more — for this card patience with a set price is the better route.

What will I get for Professor's Research Prismatic Evolutions 123/131 if I want to sell quickly?

Half of all sales fell between €1,15 and €1,87, with a median of €1,56. 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's Research Prismatic Evolutions 123/131 unrealistic?

The cheapest genuine sales were around €0,86. Offers well below €0,52 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.
