Dug at about 7-8" in a 3 story house yard overlooking the river. I thought it was junk and almost tossed it! Cleaned it up and she smiled back at me. The shank is intact, no backmarks.
Wow that is cool. Nice find for sure. Have any idea on the date? There is a book dedicated to identifying buttons at you're local Barns and Noble. Let us know if you find any info on it.
