There were 196,429,785 coins minted at the Philadelphia mint in 1917. Since the mint mark is below the date, you would have seen one if there was one and stated so. So it is not a rare coin. In grade good it is worth .10 and up the scale to extremely fine it is worth $3.00. It is not really valuable, but is a collectors item. Now there is a variety of this date 1917, that is a doubled die. It is worth some bucks depending on grade. Your chances of having one is slim, but not impossible. Look at the date with a 10x magnifier if it has a doubled date or there are lines on the date you have a winner, but only if you take it to a coin dealer to have it authenticated by a grading service, this will cost you, so see what the dealer has to say first. He should have a microscope and can tell, if it is worth sending in.
