I went back to the house that I hunted last weekend. I dug a few nice coins, I'll post those after I clean them.
This is what I think was my find of the day. A Woman's Relief Corps badge. The WRC was an official woman's auxiliary to the Grand Army of the Republic started in 1883. It appears to be hand etched.
The FCL stands for their motto: Fraternity, Charity & Loyaty
Thanks for looking!
