Not exactly sure. Badge of some type?

Found in a 1860's mining camp in Eastern California. Middle of nowhere just Sagebrush and desert. Looks like maybe something associated with farming. Bushell of wheat, pitch fork,rake,shovel? Looks like it was worn with a pin attachment.

You’ve found a horse bridal rosette (the third to be found and posted on TN in the last 24 hours!)
Here’s a link to another TN post with one very similar to yours:
