Standing out is 085 Racer, worth 20,000% more today than it cost at retail. The sets below run from 1969 to 2000. All the sets below have more than tripled in value. Half of them are up more than 7,976% on retail. The PreSchool line is the best represented here. The 1970s are the strongest decade on the list. The first Duplo sets of the late 1960s and 1970s sold for very little, and sealed ones from those years seldom turn up. That is why the oldest sets show far larger multiples than anything made since.

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