Two different types of silver dollars were issued in 1921 with very different values. This was the last year for Morgan dollars and the first year for Peace dollars. The simplest way to tell the two apart is on the reverse of a Peace dollar the eagle is standing on a rock with the word PEACE on it and its wings folded, the Morgan has the wings spread out and may have a D or S mintmark above the DO in DOLLAR.

It will depend on condition. Worst case, all silver dollar coins are worth the .77 ounces of silver in them.
A 1921 Morgan silver dollar contains 90% silver and weighs approximately 26.73 grams in total. To calculate the amount of silver in the coin: 90% of 26.73 grams = 24.06 grams of silver. So, a 1921 Morgan silver dollar has about 24.06 grams of silver.
1921 is by far the most common date for Morgan silver dollars. As of 24 February 2013, one is worth about $22 for the silver.
Circulated coins are valued at $14.00-$19.00
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. Because of its relative rarity, any apparent 1921 Peace dollar should be inspected by a professional to determine its authenticity.

Your coin is a Morgan dollar. Both the Morgan and Peace designs were struck in 1921, but the Morgan coins are much more common. Please see the Related Question for more information.
