Junior Constructor (717-1) is an exceptionally old and rare LEGO set. It has not been available online or in retail stores in good/new condition for over 2 years. Due to its rarity, the estimated value in sealed condition of $529.40 may understate its true worth, assuming one can even be found for sale. Since this set was released in 1961, finding it sealed and well-preserved is exceptionally difficult—making complete sets with intact boxes museum-grade collectibles.
There are currently no new/sealed listings available for Junior Constructor at this time.
