Inflation-corrected. Start year = 100. Pick a maker above to compare it with the market.
Drag the handles to change the start and end years. The index is rebased to 100 at the start year. All values in constant 2026 dollars (US CPI). Method: within-maker OLS of log price on year (maker fixed effects). Each sale is compared only with sales by the same maker, so a year with many expensive makers does not raise the index. Not a repeat-sales index: the data has no instrument identifier. Prices include buyer's premium as recorded. Years with fewer than 100 sales are omitted.
