I have God Of War, Arctic Proxy and Blacksmith shaders, assume they're pretty rare. Weapons wise not much. Maybe my Y1 Longbow, Necrochasm and Three Little Words. Emblems would probably be the beta one (forget what it's called) and the one you get from purchasing TTK soundtrack from the Bungie store. Ships - Vienna Singer, which I finally got yesterday! Made me immensely happy! Nothing really special but that's the rarest in my collection!
