Wow, strikingly nice Franklin, but it's a '57 pic you posted, not a '55. Nevertheless, looks to me like a type 2 reverse (beautiful eagle). I voted no to send in, but you should put this in a nice capsule to protect it. Looks like FBL. Great post!
That is a proof coin . Coneca has 2 listed ..... http://varietyvista.com/11 Franklin Halves/DDOs 1957.htm
Very nice Franklin! I'll preface this with I'm not great at grading however I might take a chance if I were you to send that in. I was looking at the coins recently sold on ebay. It would have to be a min. of a pf 66 and I think it might hit that. Not sure though. Anything less than that would not be worth it. Either way, put it in a nice plastic slab!
