Set Value (New/Sealed)

233 Light Masts was a System i Leg set released in 1958. It consisted of four metallic silver HO scale lamp posts with lattice masts.

The part counts of the masts was different per region. The United States and Canada versions included 9 light masts, the European versions had only 4 and the UK and Australia sets contained six. Based on current trends, this set could be valued near $134 within the next year.

Light Masts is an incredibly rare set. Set 233-1 has not been available for sale online or in retail stores in new/good condition for over one year. Boxes in well-preserved condition are considered museum-grade collectibles, representing the very origins of LEGO. Its true market value is likely higher than the current estimate. The last brand new Light Masts was sold on eBay.

About System i Leg 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 68 sets that ran from 1955 to 1959. As of today, 214-4 Windows and Doors Retailer Pack is the most valuable Supplemental set with an estimated new/factory sealed value of $808.
