If it is a copper-nickel clad circulation strike, it's worth a dollar.
If it has an "S" mintmark and is mint-sealed in mylar with a blue envelope, it is an uncirculated 40% silver coin worth about $6.
If it is a proof coin sealed in a hard plastic case and packaged in a brown box (also with an "S" mintmark) it lists at $6.50. It can range from $6 to $10 in auction, but usually even non-circulated rolls when sold at an auction will bring less than face value after the auctioneer's commission is taken out.
