Nearly all commemorative silver dollars have been struck in an alloy of 90% silver and 10% copper, the same metal that was used for circulating dollar coins up till 1935.
Silver "eagle" dollars issued since 1986 are made of 99.9% silver but these are sold for investment rather than as commemoratives.
One of the few exceptions would be Bicentennial dollars dated 1776-1976. Special collector versions were made of clad 40% silver. However these aren't strictly commemoratives either, because the same design was used for circulating copper-nickel versions.
No 1965 US silver dollars exist.
From 1840 to 1935 all US silver dollars are 90% silver and have .77344oz of pure silver.
All US half dollars dated 1964 and prior are 90% silver (worth about $11 in scrap silver) All US half dollars dated 1965-1970 are 40% silver (worth about $5 in scrap silver) All US half dollars dated 1971-present that are circulating contain no silver and are only worth 50 cents. (The US does strike commemorative half dollars and proof silver half dollars for collectors but these are almost always found in mint packaging, not as a loose half dollar).
U.S. dimes, quarters, half dollars, and silver dollars dated 1964 or earlier contain 90% silver with 10% copper.
it's just a common Eisenhower not a commemorative coin and none of the bicentennial dollars made for general circulation have any silver or are worth more than face value. Only Proof and collectors coins sold from the US Mint are worth more.

Well, silver is about 30$ an ounce so 120 dollars.

Are silver coins made by the US Mint. Quarters, Dimes, Half dollars and dollars struck for circulation dated 1964 and prior are 90% silver. Half dollars dated 1965-1970 are 40% silver. All US coins intended for circulation dated 1971 and later are not silver. The US has and does mint silver coins intended for collectors including the American Silver Eagle, since 1992 they have made a silver proof set and there have been many silver commemorative coins minted.
All US silver coins before 1964 were 90% silver. Peace dollars weigh 26.7 gm if not worn, so they contain about 24 gm of pure silver.

Half dollars have never been made out of pure silver but all half dollars minted before 1965 are 90% silver, halves dated 1965-1970 are 40% silver. Circulation issue halves dated 1971 and later are copper nickel and thus worth 50 cents. The US still makes commemorative half dollars such as the 90% silver proof half dollars made from 1992-present.
The silver content of half dollars was reduced in stages. They were made of 90% silver up to 1964. From 1965 to 1969 they were made of 40% silver. None were minted for circulation in 1970, and in 1971 the composition was changed to copper and nickel.
Please check your coin again. The first US silver dollars were minted in 1794. You could have a commemorative coin honoring the US Constitution; if so it will have that information and an actual minting date on it.
