Frequently asked questions

Is the English or the German Bronzong SWSH Black Star Promos SWSH091/307 worth more?

From real sales: Italian £3.63 (11), English £3.49 (16). 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.
