The Thirty-cent Prexie
Registered with return receipt, double weight
The minimum fee for registry service was twenty cents from March 26, 1944 until January 1, 1949. Return reciept service was four cents during the same period.
This cover paid double weight postage of six cents, a registry fee of twenty cents, and a return receipt fee of four cents in 1947.
This double weight cover was sent registered, return receipt requested within San Juan, Puerto Rico in 1947. As San Juan would have been a carrier post office there was no drop letter rate, and full six cents postage would have been charged.
