4-H buddy,
I don't know much on what type stuff you guy's find out there as it is a little different everwhere but here on the coast if I saw that I'd pick it up for sure cause to me like you said it looks to be worked. And with out it in my hand hard to say sometimes but I do believe that it was used for something along the lines of a celt.My dad is the indian Chief

as we mainly him for the most part have massed a very large collection.Biggest I know of in these parts as he started very young.I'll post what few I got here so it might help you decide.I'd say yes purdy sure it's been messed with by someone yours.I'll also look in a book I have to see if theres anything like it there.
Ps I know there not the same material but that shape of yours is why I say what I say!Also if you get out this way sometime I'll show you what we have massed over the years!
