Is the "young Lincoln" daguerreotype authentic?

A few years ago, this daguerreotype portrait was publicized as a portrait of Abraham Lincoln, taken when he was a young man - and years before the first authenticated photograph .

This site, " Lincoln Portrait " , makes (to me at least) a rather convincing argument for the authenticity of this daguerreotype - even though at first glance it seems quite different from the older Lincoln we are much more familiar with. And it seems (from the first link I proved to the photo) that many historians doubt that the young man is Abraham Lincoln.

Are there any people here who have a stand on whether the portrait is Abraham Lincoln or not?

It’s not the only candidate for an earlier daguerreotype of him. (Scroll down.)

Much as any portrait with an unidentified young male Elizabethan sitter is a candidate for someone suggesting they’re Shakespeare, I suspect the same is true for any gawky bloke from the 1840s and Lincoln.

My own not-professional opinion? It’s not him.

Comparing the disputed photo with the authenticated photo of the younger Lincoln, there are several differences:

[ul]
[li]the earlobe of the disputed picture hangs much closer to the side of the face than that in the authentic portrait[/li][li]there is a bump on the nose that doesn’t exist on the authentic portrait[/li][li]the angle of the tip of the nose is different and the philtrum is proportionately longer on the disputed portrait[/li][li]the upper lip is fuller on the disputed portrait[/li][li]the lower jaw is larger on the authentic portrait[/li][li]the crease in the cheek and lines around the mouth in the authentic portrait are completely absent from the disputed portrait[/li][/ul]While you could argue that the lines around the mouth are due to age, the photos were purportedly taken at most 7 years apart. Lines that deep don’t appear out of a vaccuum.
The eyes are strikingly similar and I can see why the question is asked, but I’m 99.9% sure it’s not Lincoln.
