It' nice to find a stamp with some value while searching through a lot of older stamps, starting a tedious task of checking through stamps that look identical yet are printed in different methods and different perforations, I did find two stamps, both used, one list for $215 & the other $200. Like detecting, dig thru a lot of junk, but you can and do find a treasure or two. They were scott cat. # 578 & 579. I know I will really check them again, because it seemed to good to be true? I've only counted perforations five times, couple more time couldn't hurt.
