Chelsea clock

by Bob
(New Eagle, PA)

I know its a Chelsea clock ships wheel, I am not sure wheather to get it appraised and to insure it. I did get a certificate of orgin from Chelsea. The serial number is 235252 and has Ambercrombie and Fitch, New York on top.

I was wondering if I should send it back to Chelsea to get it refurbished to be a shinny brass or leave the patina. If someone can help me on weather I should leave it as is and/or get it insured please let me know. Thanks.
