Set Value (New/Sealed)

This represents the current new/sealed value of the set Universal Motor Set since January 1976. Medium accuracy
LEGO 901 Universal Motor Set was a 31 piece Universal Building Set set released in 1976. It is also called "4.5V Universal Motor". The current value for a new and sealed Universal Motor Set is estimated at $114, with an average annual growth of approximately 3%. On the open market, a used set will sell in the range of $37 and $51, depending on its condition.
Universal Motor Set (set 901-1) is an extremely old and rare LEGO set. It has not been seen for sale online or in retail stores in good/new condition in over 2 years. Due to its rarity, the current estimated value of $114.00 may be much lower than its true value, assuming it can be found for sale. As this set was released in 1976, finding it sealed and in good condition is particularly challenging, likely driving its true value even higher.

About Universal Building Set Supplemental

The LEGO Universal Building Set Supplemental theme, active from 1969 to 1976, offered additional elements to enhance and expand basic LEGO sets. Key sets include 990-2 Trees and Signs and its earlier variant 990 Trees and Signs, which provided decorative elements to add realism to LEGO creations. The 797 2 Large Baseplates Grey/White set offered foundational pieces for building larger and more stable structures. The 103 4.5V Motor Set with Rubber Tracks introduced motorized movement, allowing builders to create moving vehicles and machines.

Supplemental consists of 8 sets that ran from 1969 to 1976. As of today, 990-2 Trees and Signs is the most valuable Supplemental set with an estimated new/factory sealed value of $182.
