I just found a pearl today

The pearl is quite nice, white, bigger than your average jewelry pearl and perfectly round...
I found it on the shore of Orman Dam here in South Dakota, I always keep an eye out for fossil shark teeth and the like out there.
It took me a long time to be sure it wasn't a small marble, but it had mother-of-pearl irridescence and no seams or holes... Also rough to the teeth. I was pretty pleased with myself, I wonder what they're worth?
