it all dip-ends on the grade and mint
1964 was the last year for silver quarters.
It is impossible to define the value or worth of a 1963 5 dollar silver certificate because there were none manufactured in that year. The last batch of 5 dollar silver certificates are dated 1953.
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.
1921 was the last year for Morgans, so 1922 is a Peace dollar. It's worth about $27.
No such coin (that is intended for circulation) exists. The last silver dollar coin was minted in 1935. The only other coin since then to use the silver dollar size was the Eisenhower dollar first minted in 1971.
The last silver certificates were printed with the date 1957. All green-seal dollar bills are worth face value only, unless they're uncirculated.
The last large dollar that was 90% silver was a 1935 Peace dollar.
With a date of 1979 the coin has no silver in it. 1969 was the last 40% silver circulating US half dollar. The coin is worth 50 cents.
The last silver half dollar was minted in 1969.
Check that coin again. The last year for Morgans was 1921. That said, if a silver dollar has been turned into a belt buckle, then all collector value is destroyed and is only worth the silver. At present, it's worth about $25.
Double check that date, because the last year for silver dollars in that era was 1935.
1978 is the last year for the Eisenhower dollar. Only proof and very high grade uncirculated coins are worth more than 1 dollar. None of the coins contain any silver. People call them "Silver Dollars" just because of the size.
