Your find is probably a tool check tag, and would have been manufactured by a brass novelty works. The same brass planchets were used for trade tokens and tool checks, etc. The integrally stamped numbers is called "incuse". It probably dates to the 1870s at the earliest, and maybe no later than WW I.
I’d think it’s a tool check tag due to the hole. But it also could be a pickers check, what farm owners would pay employees so that they could buy products at the farm’s store.
