Letters and parcels without valuable enclosures may be disposed of by him without record and not held for reclamation. (b) The Postmaster General shall return to the senders by registered mail ordinary dead letters containing $10 or more in cash, and parcels of the first class which apparently contain matter valued at $10 or more. The minimum registry fee, in addition to such other fees as the Postmaster General may prescribe, shall be collected at the time of delivery. § 4109.
