5 Cent Blue 1910 Washington Perf 12 in Exceptional condition Double line water marked (Verification help)
This has been quite the journey; can anyone help me with the identification of this stamp to see if it is in fact an extremely rare variation of the 5-cent Washington from 1910? It has perforation 12 on all sides. It has a watermark that is pretty hard to show on camera but is very visible in person; it has a big S curving through his face and downward out past his chin. The paper is the key factor here: 1. It is thick, with a night-and-day thickness difference compared to the standard issue. 2. The paper seems to have lots of tiny fibers in it. It is actually very apparent throughout the stamp, seeing little bits of blue making up the fibers of the paper, but it is easier to see when shown on the perforations. The stamp was in the possession of a third-generation stamp collector who inherited the collection after her husband died and passed them on to me. I have been going through these for months, just learning history, when this jumped out at me! If anyone could help, I would really appreciate it. This was not a random find; I am very deep into this.
