I have a few boxes of miliary stuff that I'm trying to sort though.  I am lost.  Is any of this stuff collectible or should I just list it in a couple of big lots?

Here are some of the things I've found so far....

A few Navy hats can't tell the age

Post cards from Paris in 1914

A 1919 accounting text book.  Inside of the cover is his name and it says "General Accounting Office Navy Department Division Washington, D.C.".  The strange part is that the first three pages are typed assignements and grades and all assignements are in the book.  The books is held together by a string on the inside.  This is from when he worked as an auditor for the Navy.

A certificate from 1914 saying that he is now a member of the "Amercian Flag House and Betsy Ross Memorial Association"

A small booklet that says "Report of the part taken by the Fifth Division in the St. Mihil Operation September 11th to September 15th (inclusive) 1918 Under Command of Majot General John E McMahon U.S.A"

Armband with a patch that probably meant something

An ID card from 1917 for American Expeditionary Forces

A gasoline ration card

Typed letters from 1940 about the "Military Order of the World War".

A year book and handwritten diary from 1942 when at school at Virginia Polytechnic

 
A 1941 letter about a request to re-enlist.  Appointment Letter from 1942 and other misc letters to and from the military

Personal handwritten letters from other soldiers thanking his mom for her hospitality and letters from friends
