I sell quite a few postcards and see a ton of Franklin 1 Cent stamps, but this one caught my attention because it was blue. Is it anything special? The postmark is 1907. I googled and saw other styles of blue Franklin stamps, but not this particular one. It's obviously in fairly bad shape so I'm assuming it's not worth anything...it's more just that I'm curious about it since I don't remember ever seeing one.
