Fabulous #9 1851 1c Type IV Plated Lot

heh. No sweat - you win the golden (virtual) egg.
Lets see if an appropriate emogee exists ... not really, try this..

Wow... I didn't see that one coming ... 99r2 buried in a strip of 3? I can't see the double transfer at right, and the 99r2 is indeed a total mess with inability to make out breaks in up and lower lines. Amazing you figured it out. What tipped you off?

As Dudley pointed out, you know this is a bottom right sheet margin strip. That's obvious. The right sheet margin is so big, that any plate with a centerline probably is not in play here for this being from the left-pane. So the only left pane candidate would be 100L2, since plate 2 had no centerline. So the entire list of candidates is:

98-100L2
98-100R1E, 1L, 2, 3

That's it. Those are the only positions this could be.

Then I saw the bottom of the middle stamp. The bottom left plume area is visible and very short. Even though the bottom line is obscured, it seemed to be absent - so I got interested. I'm very familiar with 99R2, so I looked for some of the key plating marks from it. I see some ornament doubling at Ornament L - faint. When I really knew, however, was when I saw the curl in the hair horizontally even with the eye. Also the dot beneath it. Those are solid 99R2 plating marks, which I'm quite familiar with. After that, I did due-diligence and checked the other positions and checked horizontal spacing and vertical alignment, just to formalize it, but I knew when I saw the curl in the head.

One thing about 99R2 is that since it is short transferred at top and bottom, it tends to be a shorter stamp than most. While you can't easily see the top here, the bottom (messed up as it is) does appear to not extend as far down as the stamps to the left and right of it. That could be due to vertical alignment, but the shortness of the lower left plume got me started in this direction.

100R2 is a Ty II in this printing. 100R2 is talked about in Neinken as being a swing position: Ty II-IIIA with the bottom line broken. I can tell you that 100R2 with the bottom line broken is a tremendously rare stamp. I had a very late impression 100R2 and the bottom line was faint, but still complete. IIIA's from there are very very hard to find.
