Dating of Daguerreotype Janet Moscrip (1792-1874)?

[USCRx]

This is a daguerreotype in my possession. I have assumed is was my g-g-g-grandmother, Janet Moscrip. It was pretty spotted, and I had it professionally cleaned last year. I'm wondering if anyone had a date range guess, based on clothing, hair style, studio, etc. I can post a photo of the case, if that would help. Thanks!

My guess would be 1850s but Jim will be more precise...I wouldn't mind seeing the whole thing including the union case and unrestored.

Just to educate me can I ask what a daguerreotype is please?

They were the first photographs ever produced commercially in 1839.
The image was superimposed on a thin sheet of copper covered in a light sensitive gel.
The image you see is what went into the camera (no negatives) & the images were always in reverse as you can see by her wedding ring.
Agree with Carol although with an older lady who's pretty much covered up it's difficult to see any detail other than the Brettelles of her bodice which are typical of the 1840/50's - early 1860's.
As Dags were superseded by Ambrotypes in 1851 my conclusion would be 1840's - v.early 1850's.

Here's the case opened and closed. Hope this helps in the dating.

Oh it is lovely isn't it...thanks for sharing. I can't add to Jim's date but for comparison my early 1860s Ambrotype can be seen here and:

The front of mine is nearly the same but black but it only has one clasp and yours has two.

Although the earliest Daguerreotypes & Ambrotypes are far superior in quality to the later albumin prints.
I much prefer them to anything else & it's nice to see one in such good condition.

I would agree with that too.. I think she looks to be in her mid late 40s. She's not yet going grey and doesn't appear to have cheek Jowls.
