LEGO 409-1 38 Slimbricks Assorted Sizes is a Classic Supplemental set released in 1965, containing 38 pieces. It is a parts pack branded as LEGO The Building Toy and consists of slim bricks, or plates, in several small formats including 1x1, 1x2, 2x2, 2x3, and 2x4. The set was released exclusively in the United Kingdom and Australia, with known alternate versions in Red/White, Yellow/Blue, and Trans-Clear/Black color assortments. Across these versions, the included elements appear in colors such as red, white, yellow, blue, light gray, and trans-clear. Based on current trends, this set could be valued near $84 within the next year.
38 Slimbricks Assorted Sizes (409-1) 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 $78.56 may understate its true worth, assuming one can even be found for sale. Since this set was released in 1965, finding it sealed and well-preserved is exceptionally difficult—making complete sets with intact boxes museum-grade collectibles.

About Classic Supplemental

Starting in the 1950s LEGO began individual parts sales, a practice that began with the Ferguson Tracktor in 1951. LEGO would supply dealers with wooden parts boxes and refill packs. These individual part sales would continue, at least in some markets, into the late 1950’s.

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 $435.
