Neat Find!
My first guess is that its an inventory tag..., for a bundle of lumber...?
My second guess is the answer = ....but, I'm real bad at math....!
Thanks for responding, DFX good guess, though it might be a little on the thin side not sure, Noah its either copper or brass i can never tell them apart, the back is plain, anduril maybe with a deal like that its got to old!!
The hole in it makes me think it was a tag for something.
(Toe tag at veterinary med school laboratory? "Just pay for your practice cadaver at the cashier." )
I'm wondering if it could have been a tag/label for box "7". Whatever went in it, cost 20c.
When restocking, they would just tell the helper "These go in #7."
More likely a tag that goes on a crate/bin for Size 7 or Item 7?
