Thank you all for the information, I'm assuming it's a WWll button, the property I found this on is owned by a WWll vet, he said he lost a couple buttons when be came home on leave in 1944. But, his dad was in WWl when he purchased the property, so it could be either. I'll have to research it and find out for sure.
Fyrffytr1- its just dirt, tiny bit of gold coloring on the back edge, the back is too crusty to see any makers mark.
