Grommety Thing

[OxShoeDrew]

These seem to be quite common. I found one on a cellar hole lip this week and almost had a stroke. It was a pure 94 between the nails.
Could it be what's left of a cloth button? Doesn't look strong enough to be a load bearing grommet...?
Thanks!

That would be a tarp hole reinforcement ring

Maybe an old spark plug ring?

Thanks, Guys..could be either...I do find tarp rings from time to time but they're flatter, thicker, and not usually at old sites. These are found pre-1930s sites. Also, I seem to find them right on the cellar hole lips, not in garages or barns.

Might be an old spacer or washer as well. I find them from time to time as well. Usually in areas that are in the 1910-1930s that I find them.
