Hi everyone,
I ran across some old stamps recently and am completely new to the art of stamp collecting. After spending a lot of time researching online I have found that there is no way for a novice to identify possible valuable stamps so I am asking for your assistance.
The first stamp I am curious about is a Franklin 1 Cent. I am hoping that somehow it is one of the valuable ones like the #594. The dimensions seem to match but I can't tell for sure. I have attached some photos(not great ones) for reference.



I also have 5 Washington 1 cent stamps that I was wondering if any might have some value. Please see attached picture.

Finally I have some Washington 2 cent stamps. Please let me know if there is anything special regarding these. Please see the attached pictures.

I have a few hundred more to sort thru, but these were the ones that jumped out at me after a little research.
Any help would be greatly appreciated.
Thank you,
Kelley
