Civil War spike

[RayIngraham]

Trying to find Civil War relics for my nephew, and came across this listing on eBay, which is purportedly a tent stake dug from the Antietam battlefield.

I have a few concerns, not the least of which is that Antietam is misspelled on the tag and the listing. I know most CW tent stakes were wood, so I don't think that's what this is.

Any ideas? Horse picket? Railroad spike? Property grid marker?

UPDATE: Thank you for your input. Does anyone know of a reputable source for dug CW relics?

That looks more like a drift punch.

I was thinking a spike out of an old spike-tooth harrow

I'd say a punch as well. the end is mushroomed from use . I does not look like a dug artifact of any type too me.
