About Classic Supplemental

Supplemental sets are the parts packs of the 1960s, sold so that builders could add to a basic set the bits they needed most. They held windows and doors in frames, plates in several sizes, corner bricks, gates and fences, turntables, wheels with axles and train couplers. Many of these parts were new at the time, and the packs were often the first way to get them, like the wheels LEGO introduced in 1962.

Supplemental consists of 140 sets that ran from 1960 to 1971. As of today, 890-2 Lockable Storage Box is the most valuable Supplemental set with an estimated new/factory sealed value of $445.
