I'd guess it's late 1800's or early 1900's. You gave no indication of its size, DVcollector. This dual-sided token may have been used in an early vending or gaming machine. My rationale for suspecting this is that it has been well used, judging from the "circulation marks" yet evidences proportionately moderate wear from handling. Those four dots remain quite prominent and may well be a clue to the establishment's name.
