A mystery stone pendant please help!!!!

Hi everyone, My name is Tony an I could really use your help on figuring out exactly what I have an if there is any value to it. So let me share the story on how I found this. About 25 years ago me an my friend Andy where out in the woods next to my house in Dighton, MA. I lived on a dead end street an back then there was nothing but wooded area. So we were doing what ever probably playing some sort of army guy game. when i looked down at my feet an there it was just lieing there in the dirt. I'm not kidding just like that it was just there. i picked it up looked at it then we ran home to show my dad, he had know idea what it was but told me i needed to take care of it, so i did. What you need to know is about the woods we were playing in. there is some history there. Before this day I have spent plenty of other days hiking through these woods with my dad. an with him we had found a bunch of indian burials an some real old stone foundations maybe to old houses of some sort scattered through out this piece of land. my dad knew alot about the burials seeing that he was chippewa Indian born on the reservation in MI. after moving to Mass. he did tons of research on our family history an lived his entire life keeping his heritige very much alive. One of his ways of doing this was becoming The Commishner of Indian Affairs in Boston,MA. If your curiuos at all about him all you need to do is google Chief White Wolf. I'm telling you about him just to prove that when he said we found Native american burial that he was right. when my town decided to build there he fought them for as long as he could to perserve the history but as I'm sure you could guess the town won an put up houses. all thats left of those woods is this strange pendant an my memeroies. I am calling it a pendant because there is a hole on the top which leads me to believe it was worn around someones neck. the front looks like an old man's face an the back looks like a floral design. I dont believe it is native american although the floral design does kinda look chippewa but i doubt it. any help is greatly appreciated Thank you so much for reading my story an offering any knowledge about this mystery of mine.
