Help ID it's origins?

This was in a box of stuff passed to me by my Grandfather.
I'd really like to know it's origins if possible and Google is not helping me.

It's about 2.5" wide and 1" high. It's not real gold and I think that is a rhynstone above the skull.
It looks like a snake passing from the right to the left. No idea what the snake is coming out of or holding with its tale.

On the Rear is says "Created and Presented by MILT EDWARDS"
Searching for Milt Edwards turned up nothing associated to this.

There are 2 of these for sale on eBay but no additional information could be found.
My grandfather was a Mason, Elks Lodge member etc and lived in AZ. Maybe from one of those organizations?

Any help would be appreciated.

Thank you
