Hey guys, great community you've got here. I'm helping a friend sell a bunch of stuff he found in his house during his move and he found this Halo Costume by "Rubies Costume Co." The tag says "Liscensed for Halo" "Authorized User". I'm just trying to figure out if it's complete (I tried to put it together but might have done it wrong, there seems to be a piece missing) and how much it is worth. These seem to range from $50 to $500 so I would really appreciate some help figuring out what I've got and you seem like the perfect people for the job. The helmet lights up, the tag says 2010. I've attached some pictures that hopefully can help id it. Let me know if you guys have any idea!
