Post new question, no US one dollar coins exist.
There is no such thing as a 1969 silver dollar. The last true silver dollars were the Peace Dollars minted last in 1935, and then the Eisenhower Dollar was struck in copper-nickel using the same dimensions as the previous silver dollars but wasn't struck till 1971.
The mint numbers are so relatively large that the silver value will probably determine the price (40% silver). The 90% silver ones (1964) will be worth considerably more.
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
There were no silver dollars issued by the US Mint in 1964.
The 1960-1964 quarters are worth about $2.50 each for the silver 1965-1969 are likely just quarters
Dates are needed, post new question.
The 1979 one dollar coins DO NOT CONTAIN SILVER and are still in circulation today with a value of one dollar.
There's no such thing as a "blue silver dollar". You're referring to a blue-seal silver certificate; these are only worth about $1.50 in average conditions despite their age and now-unusual design.
1957 $1 bills are silver certificates. In the old days, you could trade that dollar for $1 worth of silver, or silver dollars. Right now, you can sell them or keep it.
It depends, this silver dollar, which since you say has a "D" on it, which means it is a Morgan Dollar, is not worth much over its bullion value in this condition. As the price of silver has risen (about $35 per ounce as I write this), the silver value has now exceeded its numismatic value. Keep in mind that a silver dollar is NOT one ounce of silver. The coin is 90% silver and has 0.77343 of silver in them
The value of a Silver Eagle coins is determined by the spot price of silver which right now is $29.23 which would be what your coin is worth, with perhaps another dollar added depending on condition for the coin itself.
it is about 1000 dollars sell it now
