There is a few more signature as of today since I took this picture monday morning a few minutes after asking the guys to sign it. It comes with the gold edition for PS4 and a soundtrack CD.

Well as a rule of thumb I would take how much it is worth opened as is and then go from there on the signatures added value (which is very dependent on franchise hype and if there are any known names that singed it).
