If it has a D or P mint mark next to Washington's wig, it's a normal coin that has been plated and is worth only 25 cents.
If it has an S mint mark it's a proof coin that was accidentally spent. It may be a silver proof which would at least be worth about 3 bucks for its metal, but again it could be plated.
To distinguish a plated coin from a real silver one, compare its weight to a normal quarter. If you can't get hold of an accurate scale you can make an old-fashioned popsicle stick balance. A silver coin will be a bit heavier than a standard copper-nickel one; 6.25 gm for the silver coin and 5.67 for the copper-nickel one.

The quarter may be worth something depending on the ear it was minted. You can take the coin to a collector and have them appraise the quarter.
The 2006 quarter is composed of a core of pure copper with outer layers of copper-nickel. If there was truly no copper then there would be no coin. If the usual copper line is missing from the edge of the quarter it is not because there is no copper in it but because as the blank quarter was stamped out of the sheet of metal, the outer layers containing the nickel were "smeared" over the edge of the blank quarter by the cutting die and concealing the customary copper band. Scraping the edge of the coin would reveal the copper.
