These coins carry a dual date 1776-1976 in honor of the Bicentennial. They were struck during both 1975 and 1976. There's no way to tell which year because there weren't any identifying design changes.
1964 and before, dimes were made out of 90 percent silver. The same went for quarters and half dollars. And then the us mint made half dollars from 1965-1969 40 percent silver.
No Kennedy half-dollar from 1971 to date made for general circulation contains any silver.
No one keeps track of how many coins of a given type are in circulation. But given the amount of misinformation about half dollars* it's a safe bet that any that show up in circulation today would be hoarded by people who think they're valuable.(*)Myth: "All Kennedy halves are rare".Truth: Since 1971 billions have been minted.Myth: "All Kennedy halves contain silver"Truth: Only those dated 1969 or earlier have any silver. The rest are copper-nickel like dimes and quarters.Myth: "Half dollars have been withdrawn from circulation"Truth: NO modern US coin, even the horrible Susan B. Anthony dollar, has ever been withdrawn.Myth: "The Mint stopped making half dollars"Partly True: They're no longer minted for circulation but new ones are made every year for collectors.
Since 1965, US quarters have been made of 91.67% copper and 8.33% nickel. Dimes and half dollars also have the same composition.
8-13-11>>> None of the bicentennial coins 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.
The last Liberty Head half dollars were made in 1916. If you have a Bicentennial half with Independence Hall on the back, it's a Kennedy half.
Yes, proof versions of the Kennedy half dollar were made. These will have the S mintmark.
....They haven't stopped being made. New Kennedy half dollars are minted every year. 2001 is the latest year intended for circulation, but you can buy 2011 Kennedy half dollars in mint sets and in bags on the mint's website.
The dual dated dollars, half dollars and quarters were struck in 1975 & 1976
Yes the Denver mint did strike half dollars that year and so did San Francisco in proof only. 1976 half dollars made at Philadelphia don't have mint marks; the "P" didn't appear on halves until 1980.
Kennedy half dollars are not made of gold'
They're not made of anything because the first Kennedy halves weren't struck until 1964.On the other hand, 1963 FRANKLIN half dollars are made of 90% silver and 10% copper.
The bicentennial Kennedy half dollar is made of a copper-nickel alloy, special collectors coins were struck in 40% silver but they all have "S" mintmarks.
All types of half dollars from 1964 & older were made of 90% silver & 10% copper, from 1965-1970 half dollars were made using 40% silver, and 1971 to present the Kennedy half dollars are made of 91.67% copper & 8.33% nickel
So many of the dual dated half dollars were made that only proof and special uncirculated coins sold from the mint have more than face value.
No Kennedy half dollars made for general circulation after 1969 have any silver, the 1991 is just 50 cents and is still in circulation.
The 1971 through 1974 coins are only worth face value. All circulating half dollars minted since 1971 are made of copper-nickel rather than silver. As for the "1975" half, please check again. No US half dollars were dated 1975. Quarters, halves, and dollars minted both that year and in 1976 were all dual-dated 1776-1976 Bicentennial coins.
