Frequently asked questions

Is it worth grading Seaking Prismatic Evolutions 021/131?

A PSA 10 currently sells for about £99.84, raw the card sits at £2.76 — 36,2× as much. Mathematically, submitting returns £99.84 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 £1.56, across 61 fixed-price sales £3.47. 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 £2.21 and £3.95, with a median of £2.93. 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 £1.77. Offers well below £1.06 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.
