I would have to date this a bit later. Being it is a tin Type, Ambrotype is a photo on glass with a painted black back and Daguerreotype is a silver tone Coated metal photo, and was very fragile, and are truly very hard to find, and many on ebay will call what they have a Daguerrotype but are just tin type. Another way to note you have a Daguerrotype is the image is really fine and detailed, will almost pop out at you. For the most part tin types started is 1859 and fell out in the early 1900's. And these cases was the craze of the time. Tin Types are really common, cause every fair, event, and even the local Grange hall usually had a Photograher that made them. All in all Ambrotypes and Daguerreotypes are hard to find and are worth much more then the common tin Type.
