Many larger medals are struck without a collar and with oversized blanks as it requires less pressure than striking with a collar. They are then punched or lathe turned to size. Yours looks like it hasn't gone through the final trimming. I have several of these from private mints. If yours is a genuine mint product from the centennial, it may have additional value wit the right collector.
