Sixth-plate, 1850s daguerreotype in full case. Dag appears to be sealed, but there might be a few tiny mat abrasions right up against the mat edge in the upper right. No swipes or scratches noted in the main areas. Underside of glass could use a cleaning. Case is complete and intact with some leather wear. I took my pics with flash to help reduce reflections in the glass.. and uploaded direct from camera with no editing.
