The 40% proof silver set was a 3 piece.
A 1965 half dollar contains 40% silver. These coins were minted from 1965 to 1970 and have a composition of 40% silver and 60% copper. The 1964 half dollar, in contrast, was made of 90% silver.
For the 1965-70 Kennedy half, it's currently worth a little over $4. Then with the silver collectable Eisenhower dollars, those are worth about $9. No smaller denominations come in 40% silver.
A 40 percent silver quarter, often referred to in the context of U.S. coins from the 1965-1970 era, contains 40% silver and 60% copper. Each quarter weighs 6.25 grams, so the silver content is approximately 2.5 grams of silver per coin. In troy ounces, this is about 0.0801 ounces of silver per quarter.
The 40% silver Ike dollars were produced in 1971, 1972, and 1973. These coins were part of the Eisenhower dollar series and were minted specifically for collectors in a special uncirculated format. The 40% silver content came from a blend of silver and copper, making them distinct from the earlier silver dollars that contained 90% silver.
The coins struck for general circulation have no silver,but proofs an uncirculated coins were struck in 40% silver and were offered only in sets sold by the mint.The 40% silver coins have S mint marks but so do the clad proof and uncirculated coins. The best way to find out if the coin is 40% is weigh it. Weight of a 40% is 24.59 grams, clads are 22.68 grams.
1964 was the last year for 90% silver coins and 1970 was the last for 40% silver coins. Special Bicentennial (1776-1976) collectors coins were made in 40% silver. From 1992 to date proof collectors coins have been struck in 90% silver.
40 percent silver coins are Kennedy Half dollars minted from 1965 through 1969. 1964 half dollars were 90% silver and coins dated 1971 and after have no silver. The 1970 half dollar was available only in mint sets
Solid silver? No. The silver clad Eisenhower dollars are all 40% silver. But for 1973 not all S mintmarked coins are 40% silver. The San Francisco Mint did strike copper-nickel proof coins that were included in the proof sets for 1973. The 40% silver coins were struck as proof & uncirculated but were sold separately, so 3 different S mintmarked coins were struck in 1973.
The 40% proof silver set was a 3 piece.
Generally, 1965. After that, half-dollars were made 40% silver in 1965-1970. Occasionally, specially-ordered U.S. coins have also been made out of silver.
None of the Eisenhower dollars (1971-1978) that were released into circulation had any silver! Only special collectors coins sold directly from the US Mint were made from 40% silver and all of them have S mintmarks. None of the Philadelphia or Denver minted coins contain silver. The 40% silver coins were struck only from 1971 to 1976.
For 1971 & 1972 only, all S mint marked coins are 40% silver. From 1973 to 1976 the S mint marked coins in the standard proof sets are clad coins, the 40% silver Ike's were sold separately but they were included in the bicentennial 3-piece silver sets. No silver Ike's were struck in 1977 or 1978.
The Kennedy halves from 1965 to 1969 were the only coins struck in 40% silver released for circulation. The 1970-D is also 40% silver, but it was NOT released in to circulation.
The series of Eisenhower dollars is a little confusing. Special 40% silver collectors coins were produced from 1971 to 1976. No 1977 or 1978 coins were struck in silver. None of the coins made for and released into circulation contain any silver.
1964 for 90% silver but half's were struck in 40% from 1965-1970
