I got into collecting photography a few years ago, specifically vintage cased images. Really good cased images have started appreciating in value and are no longer the bargains that they used to be, but you can still pick up nice anonymous Daguerreotypes and tintypes for not too much money. An important thing to know is how to tell the difference – many people don’t know and will confuse the two, and try to sell (and price) the less valuable tintype as a Daguerreotype. The easiest way to tell the difference is in the appearance. A Daguerreotype will have a mirror finish and be hard to view directly without a black or other non-reflective color surface in front of it. Tintypes will weigh less and be clearly viewable from any angle. There are lots of other tips that can clue you in if you’re not sure, but that’s the obvious, easy distinction.
