UNOFFICIAL REGISTRATION OF NEW JERSEY STAMPLESS COVERS
By James W. Milgram, M.D.
From November 1, 1845 to June 30, 1855 there was an unofficial type of Registration of valuable letters at most post offices within the United States. The first marking is the large blue “R” applied on receipt at Philadelphia beginning in 1845. Later beginning in 1847 some post offices began to mark valuable mail at the post offices of mailing. There were other post offices which applied markings on receipt and a few which applied markings on transient mail that was registered. The author has written several articles and a book on this subject.
