The US Bicentennial Proof Set came in two versions: the normal set (1 cent thru dollar coin), and the silver 3-Coin Set (quarter, half dollar and dollar). The normal 5-coin Proof Set is worth about $7 retail - and the silver 3-coin set, $25.
The 5 coin proof set has a value of $6, the 10 coin set has a value of $15 and the 10 coin silver set has a value of $48.
Retail price is $15.00
The quarters, half-dollar and dime are struck in 90 percent silver, generally referred to as "coin silver."The silver proof quarters weigh 0.180845 oz - multiply that by the current silver price to get the value for that coin.
It is possible, but it depends on which set your coin was in. If your coin is in a standard proof set, it contains no silver. On the other hand, if your coin is in a 3 coin silver proof set with the dollar, half and quarter it is 40% silver. If your coin is loose, you should be able to look at the edge, if it is silver it will usually look more white compared to the non-silver version which will have a stripe of bright red (or sometimes pink) copper.
If the coins show any wear, the value is only for the silver about $2.00 for each coin.
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.
