Nice!!! Congrats!!!Found these today in a small cluster buried near some scattered foundation stones. Associated nails are rose and not cut.
The 68 tag looks like a livestock ID to me. Seems as though it was repurposed as a drill backing.
Quite possibly and I gave that thought. Didn't find them spread out in a line or with any others. Could have been sitting in a shed or barn that has long since vanished. And it's the first time I've encountered them although I've seen plenty of old standard heavy smooth non-barbed wire and staples. This area was farmed late 1600's through mid-1900s. The heyday for horse and cows here was post Civil War.A wire fence nail?
