Hello All Please Help If Possible

i am looking for info about these stamps I have around twenty of them all on post cards and some different tints anything you could tell me would be greatly appreciated. The postcard ink says 1908.should I remove the stamp from the post card? I want to start a collection of all of them there are 2 cent and San Francisco ones I have been reading the old postcards I think they may have belonged to my great grandparents.

That stamp in U.S. #300 the one cent denomination of the Series of 1902. You can learn more about the stamp and series here.
The "postcard ink" is the postmark and killer. In the case of the stamp you show, it appears to be machine flag cancel. Shown complete, it could be identified. Lots of knowledgeable folks here.

I collect a couple of California counties postal history, 90% of the mail in these counties between 1900 and 1920 was postcards.

i have allot of postcards and allot have that flag...dose that mean the person never received the letter?

here it is complete could it have been canceled for the fact that it was upside down?

Hi Trav,
all stamps were cancelled when used back than, to prevent second time use. has nothing to do with the stamp being up side down

ok thanks for that piece of history. onto another question I have stumbled upon...what is the deal with the red line on 2 cent stamps and green line on one cent because I have found 10 of them so far and I am only half way through the stack. 3 two cent red line Franklin, 2 one cent green lined Franklin, and 5 one cent green line washingtons. thank you all again you have tought me allot already and spiked my enthusiasm for stamps.

It is suggested not remove any stamps from their postcards and envelopes because old postcards and envelopes with old stamps make them both much more historically interesting. Too many people have removed old stamps from old postcards and old envelopes over many years making many of the stamps very common off of their original postcards and envelopes. Postal history and post card collecting are popular areas of stamp collecting since some of these intact combinations can be unusually interesting.

Hi trav, your question about the red and green line. It has been answered ad infinitum on this forum because of a few sharks that seem to think they are rare. Those lines are mostly a part of the printing process and nothing rare about them.

Hi Trav

I've collected over 60 years now and I would make a suggestion to you to consider.

If these mail is back and forth from your family members, leave everything as you found it.

Protect what you have.

Transcribe everything and put everything in date order.

Study the information on the post cards.

Trav,

Don't remove those stamps from their envelopes! They are more valuable and appealing the way they are now. Just my two cents.

thank you all...i have decided to do what stampster said and try to order all the postcards which is proving to be quite difficult... my father was adopted by this family (i already knew that) but maybe I can find out some more history on where they came from since I consider them my great grandparents. found some pretty interesting things like a drivers licence from the 1900's and that my great gramps served in the civil war. I am almost wondering if I may be wrong about "great" grand parents they could be great great grandparents.

There are a group of us that collect those 13 star flag cancels. They are fun. I concur with all the advice given so far - the stamps have no value off the postcards, but maybe the cancels are interesting and the family history surely. The Atlantic Iowa flag is a common one however.

Dose this also qualify as a cancel or do marks like these have different meaning?
