Earth Dragon Defense #2509 worth

The catalog data for "Earth Dragon Defense #2509" is not detailed enough to give a precise valuation, as the first result is listed as a general "LEGO Ninjago Set Value" [1]. However, the catalog shows a used sold value of $246.31 for that item [1]. Since the second item is unpriced in the catalog, I recommend checking the live eBay listings shown on your screen to compare the current asking prices against that sold value.
