Show Your US 1851-57 Imperforate Stamps

Is it possible to have more than one type of 1857 10 cent perf stamp on the same cover.

Absolutely. It even is possible to have different types in the same multiple.

I have been going through some of the 3c issues that I bought recently and have been neglecting even looking at them. There were 10 3c and one 1c stamp that have been sitting in the original envelopes unopened. I opened them and scanned them today. Only one has a chance to be a 10A an only one is a #11. The other 8 are #11As. This is #11. I think that I plated it strictly using the compression technique as 60L7. I would appreciate any comments.

This is the only one of that group that may be a #10A. It looks like it has some oxidation. Not sure where to start looking on this one.

Of the oxidized stamps I have plated they are either plate 2L or 3.
This isn't to say that there may be other plates where the ink has oxidized...

jaxom100, I agree with your plating of the #11 to position 60L7. Nice job with the compression technique!

This stamp looks oxidized, and it likely was printed in brownish carmine or claret. It almost certainly was not printed in orange brown. I would start by narrowing down to the non-OB plates that have inner lines and one line recut at the top of the UR diamond block. From there, a compressed image will reveal distinct curves in the right lines.

Jaxom, try a compression check against 40L2L. It looks close.

I plated the oxidized stamp. Here are some more clues:

- It is an 11A
- It's not from plate 2L

Geesh, I finally found it with 3 choices left to look at. After searching through the long list, I found it at stamp number 237. It appears to be 98R5L. I was ready to give up and start the list over again.

Hi Jaxom,

Well done! Yeah, unfortunately, going in plate number/position sequence required getting to the third to the last position of the #11A plates, but you nailed it!

Let us know how you're progressing with plating your other 11As.

Yea, it took 2 1/2 hours. Compressed about 10% of them, when it looked close. Too bad I don't have those compression charts finished. It would have saved a lot of time.

Yeah, I use compressed Chase Smithsonian images to save time on my plating. I don't remember, do you have the Chase print images?

Unfortunately, I do not have the Chase Smithsonian images. If I did, my compression charts would be a lot easier to make. Instead, I have to hunt down images. Too bad an unnamed person had to be a jerk by refusing to let me use his images, or else I would be nearly done with my charts.

I found that there was another #11 in this group. It is a relief B. It almost appears to have two guide dots. I wonder which one is correct. It also appears that the bottom line has been recut and possibly one line in upper right triangle.
