What will I get for Cobalion BW Black Star Promos BW72/101 if I want to sell quickly?
Half of all sales fell between $1.95 and $3.43, with a median of $2.81. 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 Cobalion BW Black Star Promos BW72/101 unrealistic?
The cheapest genuine sales were around $1.91. Offers well below $1.15 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.
