Standing out is 677 Knight's Procession, worth 25,102% more today than it cost at retail. The sets below run from 1978 to 2000. All the sets below have more than tripled in value. Half of them are up more than 9,374% on retail. The 1980s are the strongest decade on the list. Small knight sets from the first years of Castle, such as Knight's Joust, have grown the most. They were cheap additions when the theme began, and sealed boxes from that time rarely come up.

Below are the retired LEGO Castle sets that have grown the most in value against their original retail price.
