1c 1857 Plate 11 Stamps

Unknown to me at least, rgstamp.

I am confused with Neinken's book in regard to the top row of Plate 11. On page 470, he defines 5 known positions (1R11, 2R11, 9R11, 10R11 and 10L11). Then in Fig 22-L he shows a double transfer with a vertical line running down the left side. Later in the chapter, he shows 13 unknown positions from the top row. One of these (Postion #2) is also a double transfer with a vertical line running down the left side. Is this the same stamp as the one shown in Fig 22-L or are there 2 double transfers with an unknown position?

At the time of the Neinken book, very little was known about Plate 11.

The lack of drawings and information in the book for it, relative to other plates reflects that.

There are actually quite a few double transfers, and at least one triple transfer on Plate 11.

There is a study group working on it - but they have not yet published the results of their work.

If you go here -

then go into the database, and go to plate 11, you will see some work done on Plate 11 by our board member jaxom. That might be of help.

kiwidad, I have always considered that these were meant to show different positions. The vertical line is placed differently in each drawing, and the plating marks are slightly different although similar in many respects. It is a bit confusing, though, I agree.

Here is another #22 that I just acquired, and it looks to me like a "B" relief.

I agree.

The New York CDS has an inverted year slug as well.

Here is a #20 I recently bought. I am almost sure that it is a Plate 11, relief "T" example, but I can't determine the position. From what txstamp has said, it must come from the left pane, but that's as far as I can get. I found a good match in Siegel sale 1006, lot 1428, but that example wasn't plated either. The left guideline and the dot in the "O" of "ONE" confirmed the match. I notice also that the Siegel sale example has a wide margin on the right - perhaps that is enough to nail it down.

I agree, that looks like a plate 11 T relief.

And you correctly concluded that the left-side vertical layout line reduces it to one of position 1L through 9L11.

The Siegel stamp appears to match.

I'm sure the postmark is 1861, and it would be either March or May.

I've been searching through auction records and both the PF and PSE databases for more examples of top row Plate 11 stamps. I found this one in a Kelleher sale (there were actually several previous sales of the same stamp), described as a Scott #20, Plate 11. The stamp has a 2017 PSE certificate #1333701 supporting the description. Since only relief "T" on Plate 11 produced #20's, and this doesn't look like a "T" relief to me, I think it is much more likely a Plate 12, relief "B".
