Proof is a method of manufacture and for the most part there is no Proof mark on coins. Proof means they polish the dies, polish the blank and strike the coin twice to bring up all the details. They are specially handled and packaged. Regular coins are struck once and drop into a hopper with a whole lot of other coins.
Your coin is special because it is a survivor. Not being in great condition means that it was carried and used in commerce and might have even been in a GI's pocket during WW II. Enjoy it for what it is and think about all the stories it could tell if it could only talk.
