FAQ

Frequently asked questions

What will I get for Professor Cozmo's Discovery Holon Phantoms 89/110 if I want to sell quickly?

Half of all sales fell between £1.46 and £1.96, 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 Cozmo's Discovery Holon Phantoms 89/110 unrealistic?

The cheapest genuine sales were around £1.01. Offers well below £0.61 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 Last Sold determine the market value?

Last Sold 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.
