Robie House #21010 worth

The catalog data provided for Robie House #21010 shows a used value of $312.04 for the LEGO Architecture Set. Since the second item, "LEGO Robie House (21010-1) (Architecture)," is unpriced in the catalog, I cannot provide a specific valuation for it. Generally, the value of LEGO Architecture sets is driven by the set's rarity, condition (especially if it's still sealed), and current demand for the specific building. You can compare the current asking prices on the live eBay listings shown on your screen against the $312.04 sold value to see if the current market is higher or lower.
