indian artifact ball

Hey, I know its been a year and a day, but I'm back! This time I got a questions for ya'll. It seems that I see a lot of people posting round geofacts and asking... "Is this some kind of game piece?". And so far, 10/10 times, the answer is NO. So, my question for you wonderful people is this...

I found this in a ravine creek on my bosses land.
