X-wing Starfighter #75355 worth

The catalog data provided for the X-wing Starfighter #75355 shows a used value of $190.03 for the LEGO Star Wars Set Value [1]. Since the second item, LEGO X-Wing Starfighter (75355-1) (Ultimate Collector Series), is unpriced in the catalog, I recommend looking at the live eBay listings shown on your screen to compare current asking prices against that $190.03 sold value. Generally, the value of LEGO sets is heavily influenced by whether they are complete, sealed, or if they are part of a special collection like the Ultimate Collector Series.
