Mega Core Magnetizer #6989 worth

The Mega Core Magnetizer #6989 is valued at $295 used based on the catalog data provided [1]. Since the second item, LEGO Mega Core Magnetizer (6989-1) (M:Tron), is unpriced in the results, I cannot give you a specific valuation for it. Generally, the value of LEGO sets like this is driven by the set's rarity, condition (especially if it's Complete In Box/CIB), and demand from collectors. You can compare the current asking prices for this set on the live eBay listings shown on your screen against the $295 sold value to see where it's trading right now.
