Unless it has the word PEACE on the back, it's a Morgan dollar. 1921 is the single most common date for that design. There's more information at the Related Question.
If you check the coins in your pocket change you'll find that the reverse side of ALL US Coins is oriented 180º to the front, i.e. upside down, and they ALL have the motto E Pluribus Unum so neither of these is anything special.

If it's a 1979 Susan B. Anthony dollar it's not silver and I'm going out on a limb to say that the eagle isn't upside-down either. ALL U.S. coins minted since the 19th century have the front and back oriented 180º to each other so that the sides point oppositely when a coin is flipped side to side like the page of a book.
Eisenhower was on the one dollar coin, and it's worth one dollar.

By "upside down", do you mean that the eagle is upside down when you flip the coin side to side, like the pages of a book, or top to bottom, like a calendar? Compare your dollar to any coin in your pocket change. If the eagle is upside down when flipped side to side, just like the other coins, you have a normal silver dollar worth maybe $12 to $15 depending on condition. If it's upside down when flipped like a calendar, you could have a mint error that needs to be checked by a specialist. Note that nearly all U.S. coins use what's called "coin rotation", where the front and back (obverse and reverse) are opposite in orientation. Some other countries (Canada, U.K., EU, for example) use "medal rotation" where the obverse and reverse point the same direction. It's just a matter of what each issuer's mints chose to use.
