Frequently asked questions

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

A PSA 10 currently sells for about $195.78, raw the card sits at $1.74 — 112,5× as much. Mathematically, submitting returns $195.78 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.

Across 6 auctions the median was $0.95, across 25 fixed-price sales $1.75. 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 $1.29 and $2.10, with a median of $1.75. 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 $0.97. Offers well below $0.58 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.
