Circulating silver dollars minted up till 1935 were never made of pure silver. It's too soft and would wear out quickly so all silver coins contained 10% copper. If that's what you have please post a new question with the coin's date for a more specific answer.
If you have a 99.9% pure bullion "dollar" minted in 1986 or later, its value depends on the current price of silver. That changes daily so you'd need to check a financial or precious-metals site for the current value of 1 oz of silver.
No US Half Dollars are pure silver. The composition is .900 silver & .100 copper. For a value, the date and any mint marks are needed for an evaluation
A US silver dollar from 1840 to 1935 contains .77344oz of pure silver.
The coin has .77344oz of pure silver.
The silver value is about $6.00. NOTE: The US has never made a pure silver quarter, they are 90% silver & 10% copper.

No. The US has never and will never make pure silver dollars.
The amount of pure silver in the 1922 Peace dollar is .77344oz, all US silver one dollar coins from 1840 to 1935 have this much silver in them.
The amount of pure silver in the 1925 Peace dollar is .77344oz, all US silver one dollar coins from 1840 to 1935 have this much silver in them
Look at the coin again and post a new question. No US dollar coins are dated 1950. Also no circulating US coin was ever made of pure silver, all were 90% silver and 10% copper.
what is the current value of an 1878 silver dollar
The U.S. silver eagle is 99.9% silver with a miniscule amount of copper.
I think that you are asking about the one ounce US Silver Eagle, a .999 bullion coin with a face value of $1.00 (although, of course, with an intrinsic value far higher than that).
