In every indictment in which it shall be necessary to make any averment as to any money or any note, being or purporting to be made or issued by any bank incorporated by law, or made or issued by virtue of any law of the United States, it shall be sufficient to describe such money or note simply as money, without specifying any particular coin or note; and such allegation shall be sustained by proof of any amount of coin, or of any such note, although the particular species of coin of which such amount was composed, or the particular nature of such note, shall not be proved; and in cases of larceny, embezzlement and obtaining money or such notes by false pretenses, by proof that the offender stole, embezzled or obtained any piece of coin, or any such note, or any portion of the value thereof, although such piece of coin or such note may have been delivered to him, in order that some part of the value thereof should be returned to the party delivering the same or to any other person, and such part shall have been returned accordingly.
