I'm guessing you aren't in the United States? They look real to me, but even if they aren't, it's only 3¢.
I am guessing that your coin is a 1946-S. If so, it is worth appox 20¢ in a VF condition, also assuming the reverse is in same condition. When asking for a coin value in the future it will be helpful to post a photo of both sides. The clearer the better.
