Scott #10, If Orange Brown, Early Use. Any Opinion?

The stamp on the left, was mounted on a page with eighteen other stamps. Nine I'm sure are Orange Brown, including the stamp below right. The others, like the one in question, I'm not sure about.

I scanned them side by side for comparison.

I should be working on my plating studies...but this July date is distracting me. Could this stamp be OB, under inked?

I think a photo of this one is needed.

The alternatives would be dull red and rose, right? They don't seem very likely.

This one doesn't seem to have the ink quality or color of an orange brown. The orange red color can look similar to orange brown, but most orange brown ink is of superior quality in comparison.

Yea, it just doesn't have that "it" factor. Was hoping there might be instances of, well...of orange brown not looking like orange brown...ugh. sorry.

For my eyes, the medallion area of an OB stands out. There really is a superior quality look about it.

I got a new scanner today because I'm not happy with the color rendering of my current scanner. I hope to test it out tomorrow on some 3-cent colors. Color classification is more difficult than plating on this issue.

There is a certain range of shades just on #10s, including some that don't have that distinct, rich Ink. But I bet yours is orange red.

Orange red is a good possibility. Sometimes a scan of the back can be diagnostic, especially on some 1855-56 printings. I will try to find a scan to show what I am talking about.

Regarding the probable orange red #11 above, I resumed posting #10/11 color images to a thread I started last year, starting with an orange red/orange brown comparison. I finally got another Epson scanner that renders colors well:

Here is an image of the back of 3c stamp printed in 1856. I have never seen this paper (which is probably from a different manufacturer) used earlier than some time in 1855. It can help sometimes... Note the pattern in the paper from the paper machine web.

Thanks for the info on the paper change, Sinclair! I never noticed that.

I haven't studied paper much on this issue except to look for stitch watermarks. I have one on part India paper also.

Uh oh, I responded to Sinclair's post, but I don't see it here. Wonder where I actually posted it?

Anyway, this is another excellent tool! Thanks

I have a stamp noted as "thin paper". I haven't removed it from the page it's mounted to.
Is there such a thing?

India paper would be a type of thin paper. It's pretty rare.

I don't really think it was a paper change per se. They could have been using two different manufacturer's paper concurrently or possibly even back and forth between more than one paper maker.

The thin paper stamps are my obsession. It is generally accepted that there is a thin paper variety and a part India paper variety. Both are a thin paper about 2/3 as thick as normal paper. They are indeed scarce but not as rare as Chase suggested. The final chapter on the thin paper stamps has not been written. I hope to be the author.

Your thin paper stamp should be from Plate 1E and chances are good that it has a small Boston PAID cancel. You may send it to me and I would be happy to take a look at it.
