What will I get for Gym Badge XY Black Star Promos XY205/211 if I want to sell quickly?
Half of all sales fell between €12,89 and €18,13, with a median of €13,95. 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 Gym Badge XY Black Star Promos XY205/211 unrealistic?
The cheapest genuine sales were around €12,10. Offers well below €7,26 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.
