This article reconsiders the durable goods monopoly problem when the monopolist's marginal cost is private information. We show that the Coase Conjecture implies the No Trade Theorem: In any equilibrium in which the lowest-cost seller's initial offer approaches her marginal cost, the aggregate probability of trade must vanish. However, we also construct non-Coasean equilibria which approximate the unique outcome of the rental version of the same model. These (stationary) equilibria are comparatively efficient.
