FAQ

Frequently asked questions

What will I get for Team Aqua's Secret Base Double Crisis 28/34 if I want to sell quickly?

Half of all sales fell between $0.98 and $3.95, with a median of $1.71. 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 Team Aqua's Secret Base Double Crisis 28/34 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 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.
