Thanks for the kind words fellas.  A few more just for fun.  The wooden disks all have mound builder images.  The paired turkey image was a shell gorget and I am borrowing the image for copper use.  The smaller pendants all have authentic mound builder images, but they are used singly instead of part of a larger motif.   
Mound builder inspired.   

The copper gorget with a cross inside a sun is a replica of an authentic copper gorget found in Illinois.  
The copper gorget with a mt lion on it is a replica of a corget carved in shell and found in Missouri.
the four falcon head design was from moundville and I forget if it was a shell gorget design or carved in sandstone.
