What style is this mirror?

I see these mirrors listed as Federal, Empire, Neoclassical, Sheraton, Federal Sheraton, Empire Neoclassical......... Which one is correct or are they all correct because the style transitions from one period to another? Thank you.

Although i am not a mirror person, I refer to these as Pier mirrors, 19th century. They made this type mirror for 100 years so kind of hard to ID style. Wait for others to post.

 

Hmmmm, in looking at Willis Henry catalogue just now, he has a mirror similar to one you are asking about. Sheraton is the style, according to him, which would be 1st quarter 19th century here in USA
