Please Help Identify This Envelope, And Value It

Fairly late stampless cover between two major cities at a common rate. Retail value perhaps $3-$5 unless it was written by someone very famous.

I agree with revcollector that this is an ordinary stampless cover carried between two major cities. There was a very large amount of mail going between Boston to the north and Washington and Richmond to the south and eventually all the way to New Orleans at this time so mail postmarked in any of the cities along this line, including Philadelphia of course, would be common. $3 to $5 would be a full retail price, though if you put it up for auction you might not get a bit less. Also, as revcollector mentions, this value is assuming the content of the letter inside is ordinary business related or common chit-chat type communication. If the writer were very famous such as it being from someone like Samuel Colt in which he was describing his newest designs for his pistols or President Van Buren discussing his order for the forced removal of the Cherokee nation from the Carolinas and sending them on the Trail of Tears or such then of course that would drastically change everything.

Shawmut Bank was started in 1836 in Boston, so the letter is addressed to a relatively new firm. It grew to a 10B financial institution when it merged with Hartford Financial in 1988. It is now part of the giant Fleet Financial.

Thomas S Fullerton was the company bookkeeper in 1838!
