Insights

Released in 1980, Mineral Detector includes the red astronaut and Classic Space logos, and its early-era nostalgia has kept sealed examples in short supply; demand within the Classic Space community is steady, and non-unique minifigure design and occasional tribute reissues add some volatility to long-term returns.

Set Facts

It includes a six-wheeled ground vehicle with two sensor dishes and a red Classic Space astronaut minifigure.
The set is also called Survey Vehicle.

Collectors

Investors

“Small sturdy vehicle with twin ground-scanning radar dishes mounted on moving arms, driven by a red astronaut with a walkie-talkie. Kind of goofy with the big blocky swinging arms but I like it. Perfect companion to the Shovel Buggy. The new bar piece provides a back roll... More bar detail, and again the new clip piece is used to hold an accessory.”
