Please check again and post a new question. The US didn't mint any $1 coins from 1936 to 1970 inclusive.
1964 was the last year for silver quarters.
As of February 2018, it's worth about $2.50 for the silver.
It's currently worth about $5 for the silver. Kennedy half dollars minted 1965-70 contain 40% silver.
1965-1970 Kennedy halves are only 40% silver. Most are valued for just the silver, about $4.50.
how much is a 1799 silver dollar worth
The 1965 Kennedy half dollar is a 40% silver coin (1965-1969) but so many were made only a very high grade uncirculated example is worth more than the silver in the coin. The silver value today is about $2.70
how much is a 1924 silver dollar worth
1896 silver dollar is worth how much?
Half dollars 1965-70 are 40% silver.
A Washington silver dollar, believe it or not.
It depends greatly on the year, early silver dollar proof dollars can be worth several thousand dollars, modern silver dollar proofs of common dates might be worth $20 or so for silver scrap.
Half dollars dated 1964 and earlier are 90% silver and are worth about $11 in silver content. Keep in mind that proof, error, and key date coins may be worth much more than pure silver content. And from 1965-1970 the half dollar was 40% silver and is worth about $4.50 in silver content. Half dollars dated 1971 and later are not silver unless found in a US mint silver proof set. Note that any half dollar made during 1965-69 is only partially silver and is worth about $3. Halves dated 1971 and later contain NO silver and are only worth 50 cents.
