LEGO 404 Building Set is a vintage Universal Building Set set from 1977 valued at $410 for new and sealed sets, up 925% from an original retail price of $39.99. Annual appreciation has averaged 4.84% since release. Used copies are valued between $280 and $385 depending on condition.
LEGO 404-1 Building Set is a Universal Building Set/Basic Set released in 1977, containing 467 pieces and 3 LEGOLAND figures. It was a U.S.-exclusive release and is equivalent to set 912 Universal Building Set / Advanced Basic Set with Motor. The assortment includes black, red, yellow, blue, light gray, and trans-clear elements such as bricks, plates, slopes, wheels, hinges, rubber bands, and string, plus a black 4.5V battery box compatible with 1-prong and 2-prong connectors. Notable parts include a black Technic link chain with 48 studded links and a yellow crane bucket with a spring mechanism, and the figures appear in blue and white color schemes.
New and sealed, Building Set is worth about $410 today. It has averaged 4.8% a year since it retired, and our forecast has it near $424 next year and $504 in five. The average used price is $340 for those in good overall condition. The 3 included minifigs account for approximately 13% of the set's total value.
Building Set is a relatively rare vintage set. We have not seen set 404-1 for sale in secondary markets for over 6 months. Its market value is likely somewhat higher than our estimate.
The last brand new Building Set was sold on eBay.
Collector and Investor Standing
The Legoland figures, one dressed all in white and the other in blue, give this Basic Set its clearest identity. Collectors ask for it far more often than they own it, though its standing remains fairly modest. For investors, it sits comfortably among the ordinary Basic Sets.
