What will I get for Rillaboom SWSH Black Star Promos SWSH277/307 if I want to sell quickly?
Half of all sales fell between £1.53 and £1.80, with a median of £1.80. 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 Rillaboom SWSH Black Star Promos SWSH277/307 unrealistic?
The cheapest genuine sales were around £0.97. Offers well below £0.58 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.
Is the English or the German Rillaboom SWSH Black Star Promos SWSH277/307 worth more?
From real sales: Italian £1.80 (18), English £1.65 (20). The difference is small — language barely matters here.
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.
