What will I get for Explorer's Guidance · Championship Stamp Championship Promos 147 if I want to sell quickly?

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.
