1851-57 12c Washington

There is no extra lines in the right pane. There are two sets on the left pane. Two lines b etween row s 3 and 4 and one line between 7 and 8. Here is the text from Neinken.

jaxom - Thank you for straightening me out on that. For some reason I had thought that Jim Allen's work had found something in the right pane; alas I went back and double checked Jim's sales, and I was confused.

You are correct - the double frame line at side comes between columns 3 & 4 and also between columns 7 & 8 of the left pane only. It is, nevertheless, a key plating aid for plate 3.

Txstamp, would I be safe to assume Allen's left pane plating is correct? I am referring to the collection he sold in the Siegel auction 1265? That appears to be the place to start on the left pane plating.

I agree.

Of course, as you well know, never assume that anything is "perfect", but Jim's work definitely represents the current state of the art - no doubt.

While the sale you mention is the key starting point, Jim's material has been trickled out over time by Siegel mostly, and I do note that sale 9002 had a number of blocks, including the one I bought - I don't know if they had been sold previously.

The USPCS has published my charts for plate 1. This includes the spacing charts, guide dot charts and the full size virtual plate reconstructions.
Take a look. Here is the link:

Rick - very nice.

What you are doing is the kind of thing we need across a lot of philately - a good useful & usable transition to the digital world.

Congrats.

Mike has been able to create a new 1851-1860 Plating Initiative for the 12c Washington issue on the Stamp Smarter website for us.
Thank you so very much Mike for all your effort.

I have removed all of the 1851-60 12c issue images from the 1847 10c Plating Initiative on the Stamp Smarter website..
I have added all of my 1851-60 12c images to the new Stamp Smarter database. It is now up to date.

I would like to see everyone go and take a look. Tell us what you think.
Take note, there are 2 plates (1 & 3) and 4 panes (left and right).
Also check the upper right corner. There is an enlargeable image of the virtual plate reconstructions that I have made.
There is also a link for an introduction and a link for the charts (guide dot charts and spacing charts).

I am just starting the left pane of plate 3 so there are very few images yet.

A lot of work has gone into this Stamp Smarter project.
Your feedback is appreciated.

Very very nice. I don't go deep into plating but I have a few margin copies of the 12c that I will now go back and try to identify with this extremely useful tool.

However, I was intermittently getting an error page when switching between plates from the dropdown menu,


It might happen more often after clicking on a detail image and then going back to the main page to switch plates, but it is intermittent so can't say for sure if clicking on a detail image is related.

I don't remember seeing this in the 1c pages, but today when I went and looked, it is now happening there too. fyi..

Sorry, the server error seems to be coming from the fact that I am adding images. Your page is loaded up and I make a change and it needs to resend to the server. It notices that something has changed. That is where the error is coming from. We are aware and looking into it.

The server issue is related to something in Don's original code for other plating projects, which we borrowed for this one. It is something we have known about but have limited resources to locate and correct at this time.

I have yet to have it fail consistently so that I cannot reach a page when someone switches plates from the drop down list. Just refresh once and it usually clears.

Work is coming along on the left pane of plate 3. I found a lot of Mr. Allen's research stamps sold on 9/29/2022 Siegel Auction #1265. Resale of a lot of the material was on 6/29/2024 Siegel Auction #9002. I have one advantage over Mr. Allen, he had to find the stamps for sale and buy them where I just need the image from any past or present sale. My only cost is the time to search for images, rotate, scale, and plate them.

Here are a couple of my recent finds. First is a pair of vertical strips on cover from the first column of plate 3 right pane. Positions 51-61R3 and 71-91R3 showing the line between the plates. They were easy to plate using my guide dot chart. I needed the 81R3 and 91R3 for my plate reconstruction. I only need 2 more right pane positions now.



The second image is from 2 horizontal strips that I found from plate 3 left pane. Currently unplated, but the first strip is from columns 1-3L3 and the second strip is from columns 3-5L3. The double line between the rows 3-4 and the single line between rows 7 and 8 are going to be real helpful in this endeavor.



Don't forget to look at the new 1851-1860 Plating Initiative on the Stamp Smarter website.
See previous post for information and the link on it.

I finished adding in the images from Allen's sale (1265). There were about 40 or so plated stamps that were sold as three groups and had no images. Hopefully, I will find these in later sales. Now I am working on plating blocks and singles. I matched a stamp to position 53L3. I knew it has a double line at right, so that put it on the left pane in column 3. Then all I had to work with was the breaks in the outer frame line, It only matched at 53L3.

Then I found a block of 4 unplated that I matched to the right pane using the guide dot chart. Then I noticed a scratch in the lower left corner. That was a match to 68R3. This is the upper right stamp in the block. All 4 guide dots matched. The frame line breaks also matched. So I made 2 ID images. Since there is a column for Neinken images needed for plate 1 but none for plate 3. So I decided to use that space for a second ID Image. It is probably needed with the perforations hiding some plating marks. Most of the plating is relying on the outside frame line breaks and guide dots. Here are the first of the ID images. This is how most of them will look. Take note of the scratch at the lower left. That is unique.


Working on plate 3 left pane is like doing a jigsaw puzzle. But you do not have all the pieces, the pieces are all square, and the overall picture is a repeating image with minute differences. Here is what I have so far of the guide dot chart of the left pane of plate 3. Most of these images are from Allen's collection. Notice how they lock together. I plated the 81-83L3 (image in last post marked "columns 1-3"). Notice that the plated images surround the columns 3-4 with the double lines, columns 7-8 with the single line and the column 10 with the center line. Allen had more copies of the column 10 that was in one of the group lots. The boxes with the small images show I have the position but not a usable guide dot image. I do have 3 pairs and a block of 4 that I did not agree with Allen's plating so I set them aside for now. I have 51 of 100 positions. It is over half. Here is what I have to start my search with:

This is such an impressing work! Thanks for letting us know your progress. Also, I'm wondering:do you have a lot of these 12c stamps?

They are really expensive, that must be so hard to acquire a bunch of them for plating study...

Thank you Captain Stamp for your comments. I was beginning to wonder if there was any interest in what I am doing.

I do not own, nor could I afford any of these stamps. That is where I have an advantage over Mr. Allen. He had to find the stamps for sale and buy them. Whereas, I am just an image collector. I am using Siegel Auction Galleries' images of past and present auctions. They have a tremendous database of images from past auctions to hunt through. Plate 3 left pane has never been completed. I am hoping to do so using images from past auctions. I do not know if all the images are there to be found or not. But I am giving it a hard try to complete it.

You can see these images in the new 1851-60 Plating Initiative on the Stamp Smarter website.
