Yes I know it's Saturday :) Here is my only daguerreotype. It's not in good condition that's why I was able to purchase it for $5 many years ago.These early photographs were printed on silver or silver coated copper plates. I'm going to guess this was from the late 1850's to early 1860's. There's many sites to help you age photos I found this phototree site very helpful in dating this particular photo.
The case is wood (mostly pre-1860) I can see under the binding cloth tape holding the front and back (really not holding them anymore). The ornate matte puts it circa 1859.
