What will I get for Grumpig Obsidian Flames 091/197 if I want to sell quickly?
Half of all sales fell between £0.73 and £1.04, with a median of £0.94. 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 Grumpig Obsidian Flames 091/197 unrealistic?
The cheapest genuine sales were around £0.65. Offers well below £0.39 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.
