Frequently asked questions

Is it worth grading Seaking Prismatic Evolutions 021/131?

A PSA 10 currently sells for about €117,41, raw the card sits at €3,07 — 38,2× as much. Mathematically, submitting returns €117,41 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 Seaking Prismatic Evolutions 021/131?

Across 6 auctions the median was €1,84, across 60 fixed-price sales €4,08. Fixed price therefore fetched about 122 % more — for this card patience with a set price is the better route.

What will I get for Seaking Prismatic Evolutions 021/131 if I want to sell quickly?

Half of all sales fell between €2,60 and €4,62, with a median of €3,43. 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 Seaking Prismatic Evolutions 021/131 unrealistic?

The cheapest genuine sales were around €2,08. Offers well below €1,25 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.

Is the English or the German Seaking Prismatic Evolutions 021/131 worth more?

From real sales: French €3,11 (27), English €2,86 (57). The difference is small — language barely matters here.

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.
