Huge Linz Lunz Blue Stone Face Pin Help?

[kkjsgranny]

Good Morning,

I've listed this pin two times. I have never seen one like it and don't want to let her go cheap. I'm trying to find out if I have the name right? And if I'm trying to sell too high? Thanks in Advance!

I;m sorry I forgot to add it is signed Lunz or Linz on reverse. Also has a coat clip? or large clip on reverse. 

Thanks!
