Set Value (New/Sealed)

This represents the current new/sealed value of the set Robotics Invention System Upgrade Kit since January 2001. Medium accuracy
LEGO 3805 Robotics Invention System Upgrade Kit was a Mindstorms exclusive set released in 2001.
Robotics Invention System Upgrade Kit is an extremely old and very rare LEGO set. We have not seen set 3805-1 currently for sale online or in the hundreds of retail stores in good/new condition in over 2,835 days. Because of the rarity of this hard to find set the current estimated value of $76.82 might actually be much lower than the true value, assuming this set can be found for sale.
