Doubtful Drawings

324-G. In case of erasure, alteration or other serious cause for suspicion, the Treasury Officer shall before payment, refer to the drawer, the post office or the Currency Officer, as the case may require. Any material alteration of a Draft, after it has been drawn or endorsed, affecting the date, sum, or time or place of payment, will invalidate it; but the mere correction of a mistake, such as by inserting the words "or order" in the endorsement of a Draft will have no such effect.
