To tell if a mirror is antique, check the glass to see if it's wavy or has any imperfections. Modern glass tends to be perfect. While this can be a clue, it might just signify that the mirror is old, not antique. Another thing to check for is the reflective coating on the back of the glass to see if it has begun oxidizing and has any age scratches. Finally, check out the frame to see if it has the appearance of age. Shop a large collection of antique mirrors from some of the world’s top sellers on 1stDibs.
