Eiffel tower #10307 value

The LEGO Eiffel Tower (10307-1) is listed in the catalog with a used value of $429.50 [1]. Since the second item is unpriced in the provided results, I cannot give a specific valuation for it based on sold comps. Generally, the value of LEGO sets like this is driven by the set's rarity, condition (especially if it's sealed), and current demand from collectors. You can compare the current asking prices on the live eBay listings shown on your screen against the $429.50 sold value to see if it's a good buying opportunity.
