How much is a 1896 E Pluribus Unum coin worth?

Assuming you are referring to a silver dollar, 1896 is a common date.

They're worth about $10 in circulated condition.

Also please note that ALL U.S. coins bear the motto "E Pluribus Unum" ("From many, one") so this is not a distinguishing characteristic of a coin. The denomination, date, mint mark, and condition are the most helpful characteristics to start with.
