It's a railroad spike. I have a knife made out of one of these.

I'm sure whatever context might actually exist isn't enough for this thing.
The golden spike was the last railroad spike driven into the US' first transcontinental railroad. They really should have made the statue "right-side up" though. It'd look less like a PS1 dildo and more like a railroad spike.
