Ambrotypes were created through a similar process, using glass coated in certain chemicals, then placed into decorative cases. The difference is that while a daguerreotype produced a positive image seen under glass, ambrotypes produced a negative image that became visible when the glass was backed by black material.

Are old tintypes worth anything?

Collectors typically will pay between $35 to $350 for a good quality antique tintype in good condition. Tintypes are more common photographs of the Victorian era and thus, they are not as valuable as ambrotypes or daguerreotypes which are more rare.
