Dimes, quarters, and halves were all struck in an alloy of 90% silver and 10% copper. 1957 is a common date for these coins so unless they're in top-quality condition they're mostly worth only their melt value. That can be determined by taking the current price of 1 oz of silver and multiplying by:
Dimes: 0.072
Quarters: 0.18
Halves: 0.36
1957 nickelsPopular misunderstandings to the contrary, 1957 nickels don't contain silver. US nickels made from 1866 to mid-1942 and from 1946 to the present are made of a copper-nickel alloy, not silver. Those minted from mid-1942 to 1945 did have small amount because nickel metal was needed for the war effort. Those "war nickels" are the ONLY nickels that have any silver in them.It was 1964 when the last coins in the US were made from 90% silver.
No. The US has never made a coin with pure silver. The closest to pure silver would be American silver Eagles. These coins are silver bullion coins. They are made of 99.93% silver and .07% copper.
Please don't assume that because a coin is older it must be made of silver. Britain eliminated silver in most of its coins long before 1957; yours is made of copper-nickel like modern US coins.Please see the Related Question for more information.
Silver dollar coins (1794-1935) were never made of pure silver. It's too soft and the coins would wear out very quickly. They (and most other silver US coins) were made of an alloy of 90% silver and 10% copper. Circulating US dollar coins were made of copper-nickel from 1971 to 1999. The composition was changed to gold-toned brass in 2000. Modern "eagle" coins with an artificial $1 denomination are made of 99.9% pure silver, but these coins aren't intended for spending.
No US dollar coins were made in 1950
Quarters and most other silver US coins contained 10% copper; the last coins made of that alloy were dated 1964. The US has never made solid silver circulating coins. Pure silver is far too soft for use in coins, so it was always alloyed with copper for hardness.
Never. The US has never made a solid silver coin. They have made coins with mostly silver but they always contain other metals too.
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.
There was no silver dollar in the US made in 1957. It might be a half dollar. These are usually worth about $10-15.
ZERO, because no dollar US coins were made dated 1970
The U.S. Mint never made silver certificates because the Mint only strikes coins. Paper money is made by the Bureau of Engraving and Printing. The last silver certificates were printed in the early 1960s, but all were in the 1957 series.
Yes, there were several US silver coins made dated 2000, none though were intended for circulation. There were silver eagles made ($1 coins sold as silver bullion and are 1 troy ounce of silver), along with silver proof sets (with 90% silver dime, quarters and half-dollar) and a few silver commemorative coins made. Not to mention many foreign silver coins.
