OK...here ya' go...
Alright, I know this is an old thread, but I had not seen it until someone revived it recently...
Not sure that posting this will create the same kind of buzz and controversy as it did when I first found it about 5 years ago as I posted it on several artifact forums.
Here's what I DO know. Where I found it. The site is normally under about 10 feet of water, but because of low water levels, the site was visible. It's within a about 1/4-1/2 mile of a MAJOR Native American village (now under water). I know the other artifacts I found with it that day. And it simply is not a spot, in my humble opinion, where someone would salt it. And it certainly appears to have aged patina vs a fresh new knapp.
I can tell you. I have had a number of experts look at it. One, in particular, who is WELL respected in the field feels that it is authentic, but he would NOT personally paper it simply because he was not going to put his name on something that "supposedly" does not appear in the history record. So be it.
I have also looked at EVERY eagle/thunderbird effigy I can come across, and everyone is done in a much more clear distinct style and design from what I have. I know where I found it, and the context in which I found it, and NOBODY can tell me that it's not authentic.
OK, here are the pics, I'll let everyone draw their own conclusions...for the record, I've been hunting Native American artifacts for about 36 years.
And here are all of the other items found that day in the same spot...
