The "Mercury" coin is a dime. In addition the P mint mark was first used on $1 coins starting in 1979 so that letter can't be on a 1921 dollar. A 1921 Morgan Dollar (eagle on reverse with spread wings facing forward) is the most common silver dollar and is valued by its silver content. A 1921 P Peace Dollar (eagle perched in profile) is one of the harder dates to find and is worth at least $50 badly worn and a few hundred if uncirculated.

About 23.00$ depending of the price of silver....
In average condition the coin is worth $15-20.
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.
There is around .77 ounces in a 1921 US silver dollar.
Sorry no such coin.
It will depend on condition. Worst case, all silver dollar coins are worth the .77 ounces of silver in them.
Two different One Dollar coins were issued in 1921. A Morgan dollar and a Peace dollar. In general the Peace dollars have higher values.
The High Relief coin is the 1921 Peace Dollar, not the Morgan. Circulated examples are $75.00 to $180.00, depending on grade.
