Tintype, Unidentified Man

We have a trunk of old photographs and I found this small tintype at the bottom of the trunk this morning. It's 1.75" h x 1.00" w.  Date and subject unknown.

Original scan (R) and auto-corrected (L) scan:                                                                                

Unknown Man in Formal Attire

No clue who this very well-dressed gentleman is.  The photo has faded and has a lot of "silvering" on the surface.  I included the original scan and one that has been adjusted.
