What will I get for Reshiram GX SM Black Star Promos SM137/248 if I want to sell quickly?
Half of all sales fell between £4.41 and £7.93, with a median of £6.26. 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 Reshiram GX SM Black Star Promos SM137/248 unrealistic?
The cheapest genuine sales were around £2.98. Offers well below £1.79 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.
