What's the Oldest Man-Made Article that You Own?

[GradyPhilpott]

I thought this would be an interesting exercise.

My item isn't available at the time of this posting, but I'll go and get it out of its safe place later today.

In the meantime I'd like to see what others have that's very old.

This doesn't relate to how long you've owned the item, only the age of the item and it must be man-made.

In other words, an arrowhead would be okay, but a fossil would not.
