How this list is made
Retail prices are adjusted for US inflation (CPI-U) to today's dollars where the inflation table covers the release year; newer sets are compared with their price as it was. Estimated market values are ranges from marketplace data, for orientation only, and the "vs retail" figure is computed from the ends of the range. Only sets with a US retail price of at least $10 and 50 or more pieces are listed.
