Just kidding! Make sure you don't give them away. Take them to Comic Con or something and have someone look at them. They will probably never be more valuable than they are now, with the game making such a huge come back.
I know, I even referenced Seinfeld’s soup nazi. Yea, I will not just sell them unless the person actually fingers through then and gives a knowledge based evaluation, I have tried selling these before but it was a nightmare.
