Another unusual backyard find

[EDavis]

Did a quick backyard search yesterday and pulled this odd piece out, it’s about the size of a nickel with a white patina and looks like gold dots on front and back. Anyone with an idea, I could use them. Thanks! Erik of Tell City, Indiana

Looks kinda like a seashell. Maybe part of an old jewelry piece!
