Black "SHIP 14 1/2" straightline handstamp on May 29, 1827 Boston folded letter to New Orleans with manuscript "P. Illinois"

This cover was carried from Boston to New Orleans by a non-contract ship. The mail was taken off the vessel at the
Balize, and turned into the post office, at the entrance to the Mississippi River. It was thereupon marked SHIP and
rated 14 1/2 cents [121/2 cents for the distance 80 -150 miles + 2 cents hip fee), and placed in a closed bag for the trip up the River.

The Mail Route fiction only applied to ships sailing from New Orleans to Boston, Philadelphia or Providence, not to
Vessels sailing from these ports to New Orleans.

Red "SHIP" straightline on folded letter to New Jersey with manuscript "8" and "Ship Illonois." Datelined February 5, 1831. Carried on the non-contract ship Illinois.

Rated as under the pre-Mail Route system: New Orleans to Rahway, NJ via New York. No charge for distance from New Orleans, down the Mississippi River, along the Atlantic Ocean coast and across Long Island Sound. Rated 8¢ [6¢ for distance not over 30 miles - NYC to Rahway + 2¢ ship fee].

Noted by Cal Hahn as earliest reported receipt for a valuable letter is this one which reads:

"Marshall Post Office Dec. 1, 1840
I do hereby Certify that Messrs. Gorham & Brown have this day deposited in this Office to Mail a letter addressed Higginson & Clapp of New York Containing Two hundred dollars in bills of different banks. Chas. D Smith P.M."

This note signed by the postmaster attested to the fact a patron deposited into the mails a letter containing two hundred dollars, several years before Registered Mail was adopted.

In the Postmaster General's Report of November 17, 1828, Mclean wrote that "It may be advantageous to the public and the department at some future time, for it to become the insurer of moneys transmitted in the mail, being authorized to charge a higher rate of postage in such cases to indemnify for the risk incurred. To guard against frauds, this responsibility must necessarily be limited to packets mailed at principal offices, under such regulations as shall afford the greatest possible security"

In the mid-1800s, concerns over the loss of valuable mail prompted the Post Office Department to introduce an official registration system on July 1, 1855, for a fee of five cents.

However, in the decade prior, an unofficial system for registering valuable letters was adopted at the Philadelphia post office from 1845 - 1854. The unofficial registration system spread from Philadelphia to other post offices throughout the country. Postmasters played a key role in this process, marking valuable letters with an "R" handstamp and recording their details. Although no fee was charged, these letters were tracked and handled with greater care.

This cover is an example of a manuscript "R" notation.
