We introduce a small modification to a fundamental model of money in order to select among equilibria. It turns out that intrinsic and extrinsic properties of money have implications for equilibrium selection that are absent from other settings where coordination matters. In particular, the time discount factor matters not only for determining whether money is better than autarky, but also to pin down the conditions under which money is the unique  quilibrium. As the time discount factor approaches one, the economy tends to the e¢ cient outcome.
