Sphinx Secret Surprise

About Sphinx Secret Surprise

Sphinx Secret Surprise (5978-1) is a LEGO Adventurers set released in 1998, currently averaging $158.21 used on BrickLink. It comes with 7 minifigures worth a combined $33.04. The set has retired from retail, so secondary market is the only option. The full parts inventory runs 166 pieces.

Part-out value

The minifigures account for about 21% of the set's value ($33.04 out of $158.21). 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 $450.00 vs $158.21 used — a 184% premium. If you have this set new in sealed box (NISB), price it accordingly.
• This is a vintage set (1998). Condition of the box and instructions significantly affects value. A complete set with original box and instructions can sell for well above the average.
• 7 minifigures at $33.04 combined value. That's a solid minifig haul — consider listing the figures individually on BrickLink where per-figure prices tend to be highest.
