PRR token? (bar car)

I have a brass token with P.R.R. on one side and blank on the other side. Is this token someway associated with the Pennsylvannia railroad? Would be thrilled to find out.
Thank you.

Could this be a baggage check without the stamped number?

My father is retired PRR, in the passenger division. He remembers those tokens were used in the "bar cars". If you were to buy a friend a drink, the bartender would place a token with your friend, meaning he was to get a free drink.
