If you're using the term "silver dollar" to mean one of the small-size Sacajawea dollars introduced that year, it's brass, not silver and is only worth $1.
If you have a large (40 mm) coin that says 1 oz fine silver on the back, it's a bullion coin worth slightly more than the current price of 1 troy ounce of silver. It's sold to collectors and investors rather than being used in commerce; the $1 denomination is artificial.
A "dollar" made in 1221 doesn't exist, so there is no value. The dollar is US currency and the US was not established until 1789. Money in 1221 was different than it is today and not made of silver. Each coin was hand casted and made in 1221.
There is no silver in a 1972 US half dollar.
You are probably asking about American Eagle silver dollars. These are worth about the spot price of silver. Currently they are worth about $32.
There is around .77 ounces in a 1921 US silver dollar.
Numismedia lists the value around $7 dollars for clad(non-silver) and $65 for silver proof sets as of a 5/2012.
