Two kinds of US silver dollars were struck in 1921, Morgan dollars and Peace dollars. The one you have is very important to the coin's value.
To tell the difference between the two, look at the the reverse (back) of the coin. On Morgan dollars the eagle's wings are spread out. On Peace dollars the wings are folded and the word PEACE appears on the rock the eagle is standing on.
The 1921 mintage of Morgan Dollars almost equaled the production from all the previous years so to collectors they are extremely common. 1921 Peace Dollars were only minted during December of that year so that's a very rare date for Peace dollars.
1921 Peace Dollars were only minted in Philly, so they don't have a mint mark. If you have an 'S' mint 1921 Peace Dollar, it's a fake. Get a professional appraisal.
E Pluribus Unum, Liberty
As you can see from your pocket change, ALL U.S. coins carry the motto E Pluribus Unum ("Out of many, one") and the word Liberty so that's not a piece of information that helps to ID a coin. It's better to provide the date, condition, and mint mark as a starting point.
"Silver Eagles" are bullion coins containing 1 troy ounce of 99.9% pure silver. They were first minted in 1986 and are only sold to collectors and investors.

A 1921 silver dollar with the eagle's wings are folded would be a Peace dollar. This design was put into production at the end of that year and is much less common than the 1921 Morgan-design coin.
