Pennsylvania Auctioneer Practice Exam

Patina refers to the age-worn finish or sheen produced by the natural processes of age, wear, and polishing on a surface. It is often considered desirable in certain antiques or art pieces as it adds character and authenticity. Option A (art appreciation term) is not correct as patina refers more to the physical appearance of an object rather than a term used for discussing art. Option B (artist's signature) is unrelated to patina, which is about the surface quality of an object. Option D (art restoration technique) is also incorrect as patina is not created through restoration techniques but rather develops naturally over time.
