In circulated condition, the state quarters do not have any added value. And since so many of them were minted, they probably never will (in your lifetime). However, uncirculated quarters from some of the states have already increased in value -- some as high as $30 per roll (of 40 coins). Generally speaking, you will only be able to sell these coins in the future if they are still in their original rolls, or have been carefully stored in airtight tubes. You can get an idea of which ones have increased in value here : http://www.workingmancoins.com/ForSale/Quar50St.htm (the ones listed at over 50 cents apiece are the ones that have increased in value)

State quarters were minted by the carload so anything you find in circulation won't have any extra value.
If they are old enough yes, but all silver quarters are worth more than face value.
Any quarters minted before 1965 contain 90% silver and are worth several times face value.
Do you mean 1,997 quarters, or quarters from 1997, LOL? In any case they're worth 25¢ each. Out of curiosity, because these are readily available in pocket change, what made you suspect they are valuable?
