Yes.
NO!
no it is not
First you must determine if the reverse is upside down. All US coins are struck as "coin turned" meaning the reverse is upside down from the obverse. lay the coin flat on a table with the obverse up, turn it from left to right. If the eagle is upside down this is normal. If it's not, you have whats called a "Rotated Die" error that must be seen for an assessment of value. In general, the 1890 Philadelphia issued Morgan (no mintmark) is considered common. Circulated coins run from $30.00-$40.00 depending on the grade of the coin.
The U.S. did not issue any $1 silver certificates dated 1953.
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.
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.There's more information at the Related Question and Link below.
Yes, it is. Canadian coins are struck as what's called "Medal Turned" meaning both sides of the coins are right side up turning the coin left to right. Our US coins are "Coin Turned" and are opposite. One side is upside down.
It's probably .999 (Fine Silver) being read upside down!
Eisenhower was on the one dollar coin, and it's worth one dollar.
All 1967 US quarter dollars have the eagle upside down.
Old mirrors were coated in silver, behind the glass. Nowadays they use a different substance.
