Only lots with a final price of at least £20 are counted, and only a week with at least 20 ended listings is included, the same floor the /sold-prices page uses so no row is a median over a sample too small to trust - this also excludes the collector's first two weeks (2026-07-13, 2026-07-20), before it reached a steady weekly volume, and always excludes the current, still-accruing week, since a partial week is not comparable to a finished one. Still an early series: check /sold-prices for how many comparable weeks currently qualify before treating any single week-on-week move as a real market signal.","generated":"2026-10-09","rowCount":9,"rows":[{"weekStarting":"2026-08-03","lotsSold":578,"medianPriceGbp":550,"priceP25Gbp":275,"priceP75Gbp":1350},{"weekStarting":"2026-08-10","lotsSold":521,"medianPriceGbp":475,"priceP25Gbp":250,"priceP75Gbp":975},{"weekStarting":"2026-08-17","lotsSold":528,"medianPriceGbp":450,"priceP25Gbp":275,"priceP75Gbp":925},{"weekStarting":"2026-08-24","lotsSold":572,"medianPriceGbp":500,"priceP25Gbp":275,"priceP75Gbp":1100},{"weekStarting":"2026-08-31","lotsSold":587,"medianPriceGbp":475,"priceP25Gbp":250,"priceP75Gbp":1200},{"weekStarting":"2026-09-07","lotsSold":474,"medianPriceGbp":475,"priceP25Gbp":250,"priceP75Gbp":1050},{"weekStarting":"2026-09-14","lotsSold":539,"medianPriceGbp":450,"priceP25Gbp":275,"priceP75Gbp":1000},{"weekStarting":"2026-09-21","lotsSold":575,"medianPriceGbp":500,"priceP25Gbp":275,"priceP75Gbp":1150},{"weekStarting":"2026-09-28","lotsSold":475,"medianPriceGbp":500,"priceP25Gbp":250,"priceP75Gbp":1150}]}
