FAQ

Frequently asked questions

What will I get for Rillaboom SWSH Black Star Promos SWSH277/307 if I want to sell quickly?

Half of all sales fell between $1.90 and $2.37, with a median of $2.37. 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 $1.28. Offers well below $0.77 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: English $2.44 (25), Italian $2.37 (19). The difference is small — language barely matters here.

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.
