This is my first post so please go easy on me :D
I have 4 books of fairly old stamps which span every country from around 1900. I know old doesn't mean valuable and I wont post pages of photos but I thought some of the stamps from the USA section of the books may be of interest/value. Below is a selection of the stamps in that section.
Can anyone tell me if any of these stamps are of value or are of interest please?
Thank you for your help.
