Frequently asked questions

What will I get for Professor's Research Brilliant Stars 147/172 if I want to sell quickly?

Half of all sales fell between $1.12 and $2.32, with a median of $1.54. 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 Brilliant Stars 147/172 unrealistic?

The cheapest genuine sales were around $0.95. Offers well below $0.57 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.
