What is the value of a 1878 silver dollar E Pluribus Unum edition?

Answer 1

It's a very common mistake that most people make, but there is no such coin as an E PLURIBUS UNUM coin of any type.
E PLURIBUS UNUM is a NATIONAL MOTTO that appears on all most every coin ever made by the U.S. and all modern coins, just look at your pocket change. All Morgan dollars (1878-1904 & 1921) regardless of date have this motto on the obverse of the coins. 1878 is the first year of issue of the Morgan dollar series with 4 different reverse types. All coins need to be seen for an accurate value, but circulated coins have values of $30.00-$100.00 depending on the grade an type of the coin.
