Air Temple #3828 worth

Based on the catalog information provided on your screen, the Air Temple #3828 is listed with a used value of $233.25. Since the second item, "LEGO Air Temple (3828-1) (Avatar: The Last Airbender)," is unpriced in the catalog, I cannot provide a specific value for it. Generally, the value of LEGO sets like this is driven by the set's completeness, condition (especially if it's sealed), and current demand for the *Avatar: The Last Airbender* theme. You can compare the current asking prices on the live eBay listings shown on your screen against the sold value of $233.25 to see if it's a good buying opportunity.
