If it is a US nickel, it is 25% nickel, 75% copper. If it is a Canadian nickel I believe it is 100% nickel.

This tradition goes back hundreds of years. Coins made of precious metal have ridges or lettering on the edges so unscrupulous people cannot scrape a few cents worth of gold off the edge to sell and then spend the coin for its full value. Base metal such as nickel, copper, aluminum, and zinc have such a low value it would not be worth your time to 'shave' a nickel. Even though dimes, quarters, and half dollars are no longer made of silver the edge reeding has been retained. The Anthony and Sacagawea Dollars have smooth edges but the Presidential Dollars have lettered edges.
The British 2004 Executive Proof coin set, issued by the Royal Mint, consists of 10 coins as follows - £2 Bimetallic (nickel-brass) "Penydarren Engine" £2 Bimetallic (nickel-brass) edge inscription "STANDING ON THE SHOULDERS OF GIANTS" £1 (nickel-brass) "Forth Rail Bridge" 50p (cupro-nickel) "Sub four minute mile" 50p (cupro-nickel) "Britannia" 20p (cupro-nickel) 10p (cupro-nickel) 5p (cupro-nickel) 2p (copper plated steel) 1p (copper plated steel) There were 4,101 sets issued.
This sounds like an approx. 90% off-center strike error. These regularly sell for about $10 to $15
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.
Look at the coin's edge. It's not silver, it's copper-nickel. All copper-nickel half dollars dated 1971 and later are only worth 50¢ if they're in circulated condition. Uncirculated, perhaps a dollar.
