It's only 90% silver and 10% copper, value is about $3.00
Um... it is impossible for it to be all silver. The vast majority of Bicentennial quarters are copper-nickel and worth only 25 cents. Some Bicentennial quarters with an "S" mintmark are 40% silver. If you found a Bicentennial quarter in your pocket change chances are it isn't silver. Unless it is in mint packaging saying it is silver, it is most likely not silver.
25 cents. It is made out of copper-nickel, contains no silver and is worth only face value. They are incredibly common and can easily be found in pocket change.
The U.S. Bicentennial was in 1976 (remember when the Declaration of Independence was?)You have an ordinary silver quarter from an ordinary year. It's worth about $3 for its silver content.Bicentennial coins found in circulation are dual-dated (1776-1976) and are made of copper-nickel, not silver, so they're only worth face value.
Anything found in change is worth face value only. No circulating silver dimes have been made since 1964. All 1976 dimes, including those made for Bicentennial sets, were struck in copper-nickel.
Unless these coins are proofs or silver proofs, they are really only worth a quarter each. There are no rare dates in the state quarter series and can easily be found in uncirculated collection.
Silver is traditionally found as a byproduct of copper mining.

it is not made, it is found!
Silver is found in elemental form. It has also been found in ores such as Horn Silver and Argentite. The sources for commercial silver (such as jewelry and serving ware) come from copper-nickel, copper, lead-zinc ores, gold and lead. It's drawn from the sludge of anode wastes that come from electronic copper refining.
Sterling silver contains a little over 7% copper and silver plate often has a base of copper or an alloy containing copper. Copper corrosion and some copper salts are green, as in the popular verdegris patina on outdoor copper scupture or roofing. I have found green corrosion on some of my silver plate, which I believe is copper sulfate and due to the reaction of sulphur compounds (found in many foods and also found in newspaper, so don't pack silver in newspaper!) with copper exposed by the wearing away of the silver plate.
The vast majority of 1992 quarters are not silver and are the standard copper-nickel composition. If your coin was not found in a silver proof mint set, most likely it is not silver but rather copper-nickel. If your coin was found in a silver mint proof set, leave it in its packaging and do not remove it. However, if you think that your coin is silver, there are a few tests to see if it really is silver. First off, your coin should have an "S" mintmark on the right side of George Washington's head by his ponytail. If your coin lacks this, it is not silver. However, even if your coin has an "S" mintmark doesn't make it silver, your coin could still be a copper-nickel proof. What you need to do then is look at the edge of your coin by the reeding. A copper-nickel coin will have a line of brownish red copper through it, a silver coin will not and a silver coin will appear 100% white. If there even is just a little bit of copper showing, it is copper-nickel and not silver. However, if your coin is one of the silver proofs, it is worth about $5.25 for the silver content and perhaps as much as $6 or 7 if still in mint-state condition.
Silver is found in veins underground. It is also found in trace amounts in zinc, lead, gold and copper ores. Silver can also be found with other minerals like sulfur and arsenic.

copper, silver and carbon are not real ores but could be found as pure elements: carbon as coal, or diamond. Silver as nuggets. Copper as native copper specimen. Iron is almost never found in the free elemental state, and should be extracted from iron ore, which is not iron, but mainly made of iron oxides.
