The best thing to do is buy a copy of A Guide Book Of United States Coins referred to as Red Book. Most coin dealers have it and so do book stores. This will give you what your asking for.
any quarter prior to 1961 is currently worth at least 2 dollars in silver content
There is no such thing as an E Pluribus Unum Silver Dollar. That is simply the motto of the US, it does absolutely nothing to identify the coin other than to say it is from the US. But any US silver dollars dated from 1935 and prior are worth at least $33 or so for the silver content, any dollar coins minted after contain no silver and are only worth face value unless in proof condition.
Yes. All U.S. dimes (quarter and half dollars) dated before 1965 are 90% 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).
In theory it is the Federal Government, in practice though, no one. Prior to 1933, one dollar was equal to ~1/20 of an ounce of gold (or ~3/4 an ounce of silver). Anyone could take a paper gold or silver certificate to a bank (or the US treasury) and get gold (or silver) for their paper money. From 1933 until the 1970s, the US dollar was equal to ~1/35 of an ounce of gold, however, private citizens were not allowed to own gold and so you could not redeem paper dollars for gold coin. However, until ~1968 (the minting of 90% silver US coins stopped in 1964, but silver certificates were redeemable in silver dollars until 1968) the US would redeem paper dollars for silver at the rate of $1 for ~3/4 of an ounce of silver. All US quarters, dimes, half dollars and dollars dated 1964 and prior are 90% silver and they are set at a rate so $1 (be it 4 quarters, 10 dimes, 2 half dollars, etc.) would equal ~3/4 of an ounce of silver. However, by 1968 the government's stock of silver ran out and paper dollars could not be redeemed for silver dollars. Both worthless copper-nickel coins (the ones we have today) and silver coins circulated until the late 1970s when a large increase in silver price meant that silver was worth more than face value. Today, the dollar is essentially worthless, completely unbacked by any commodity such as gold and silver. The Federal Government "guarantees" the value of the currency only by agreeing to accept it for tax purposes.
Depends on the year and denomination of the coin. For coins intended for circulation: Dimes, Half-Dollars, Quarters and Dollars dated 1964 and prior are 90% silver Half-Dollars dated 1965-1970 are 40% silver Nickels dated 1942-1945 AND have a large mintmark over the Monticello (either a P, D or S) are 35% silver
There really aren't any that could be considered rare. The things to look out for though are: 1964 and prior quarters, dimes and half dollars, these are 90% silver 1965-1970 half dollars, these are 40% silver. Other than that, there really aren't much that are rare, unless you want to count minor die varieties.
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.
US circulation coins prior to 1965 were made of coin silver, not sterling silver. Coin silver has more copper in it for hardness, so that the coins wouldn't wear out as fast.
No silver dollars were minted in the years 1929 through 1934 due to the economic conditions of the Great Depression and a lack of demand for silver coins. The last regular issue of silver dollars prior to this period was in 1928, and the next series was not produced until the 1934-1935 years, which marked the beginning of the Peace Dollar series.
It is 90% silver and contains a little over 2 grams of silver.
It doesn't. 1970 was the last year the US mint made half dollars for circulation in silver (halves dated 1964 and prior are 90% silver, those dated 1965-1970 are 40% silver). No 1971 half dollars are struck in silver.
