Frequently asked questions

What will I get for Trevor XY Black Star Promos XY33/211 if I want to sell quickly?

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.
