 If you're fortunate enough to still have the original BOX that the robot came in, depending upon the condition, it could add well over $1000.to the overall value of the toy, and of course the better the condition of the box, the higher the premium.The best example (and most rare due to the dark green plastics and accessories included) of a mint-in-box Big Loo was sold in 2017 for a record $6495.00 on Ebay by the proprietor of BigLooRobot.com (also the exclusive supplier for exact high quality replicas of the original instruction sheets), and regularly offered museum quality robots with accessories are selling for $2500.
