About Alien Avenger

Alien Avenger (6975-1) is a LEGO Space set released in 1997, currently averaging $109.16 used on BrickLink. It comes with 4 minifigures worth a combined $36.90. The set has retired from retail, so secondary market is the only option. The full parts inventory runs 113 pieces.

Part-out value

The minifigures account for about 34% of the set's value ($36.90 out of $109.16). The remaining value is in the parts and the set as a complete package. Selling complete will likely net more than parting out unless you have specific demand for the individual figures.

Seller notes

  • Sealed copies sell for $461.59 vs $109.16 used — a 323% premium. If you have this set new in sealed box (NISB), price it accordingly.
  • This is a vintage set (1997). Condition of the box and instructions significantly affects value. A complete set with original box and instructions can sell for well above the average.
