Above the eagle I cant make out the engravment that appears to spell Pluribus Unum. I would greatly appreciate the help to Identify this coin.

Answer 1

they made trade dollars in the years 1873 to 1878, and proofs only until 1884 or 85.    But your general description matches what a trade dollar looks like. The date you mention is  wrong though.
