Dating a daguerreotype picture

Can anyone tell me of someone in the Cincinnati area that is pretty good at determining when an old daguerreotype photo was taken from its case and the clothing on the subject.Also hoping they are pretty good at judging a person's age from photo. I am interested in determining when this was taken and approx age of subject. I have a picture of the daguerreotype in its case and out of its case.

Thank you for any assistance.
