No US dollar coins exist dated 1906. Also the coin can't have a "P" mintmark because the first US coin to use it was the 1942 silver Jefferson nickel. Look at the coin again and post new question.
The date of 1891 would make it a Morgan silver dollar. Assuming the coin is circulated and does not have a mintmark, current values are from $25.00-$50.00 depending on the condition (grade) of the coin.
Please be more specific, which mintmark?
There are no 1971 peace silver dollars. A circulated 1971 Eisenhower dollar is worth about $2. An uncirculated one is worth about $5. A silver collectors edition (with an "S" mintmark above the date) is worth about $10.
The James Madison Presidential dollar is made of brass, not silver, and is worth one dollar.
Most coins are not silver, unless your coin has an "S" mintmark, it is copper and nickel and only worth $1.
If it has an "S" mintmark, it may be silver and worth up to $8.60 at the time of writing, however, if it doesn't have an "S" mintmark, it isn't silver and is only worth $1.
Need a DATE to go with the "O" mintmark of the silver dollar. Post new question.

What is a silver dollar from 1702 worth today
Are not silver and have no value over face unless they have an "S" mintmark (which means they were not intended for circulation) or in a mint set.
Generally not. When it comes to silver dollars, usually the Philadelphia mint (which used no mintmark) are more common than the branch mints. Nearly all Carson City silver dollars ("CC" mintmark) are worth a premium over their silver values, and there are a handful of San Fransisco silver dollars ("S" mintmark) worth several times their silver values. However, it all depends on the year of the silver dollar.
When talking about US coins silver dollars and dollars with the CC mintmark are generally worth more.
Look on the back below the DO in DOLLAR. It could be black or there could be a small O, S, or CC mintmark. Value as of June 2012: No mintmark:$52 "O" mintmark:$156 "S" mintmark:$52 "CC" mintmark:$540
