I have one Daguerreotype, possibly two. The one photo I know is a Daguerreotype is tiny and is without a frame. The 2nd photo may be a true Daguerreotype with a photo-electric finish. I only wish I had purchased these earliest types of photos when they were selling modestly. The Daguerreian Society has some history you may be interested in.

Black and white photos are my favorite because they give beautiful depth.
