About the Bank Note. The 1000 dollar bill with the infamous “8894” serial number comes from a firm that copied the original with the above serial number to use for advertising purposes. These notes were reproduced before Congress passed the “Hobby Protection Act” requiring the words “copy” or “Replica” on reproductions of  paper money. The “8894” copies today are commonly found in packages of play money along with other reproductions of private issue currency. From the late 19th Century to the 1950’s, reproductions of Bank of the United States currency were distributed, often with an advertising message printed on the back. Since the notes are not official U.S. issues, it isn’t considered counterfeiting to reproduce them. Genuine examples of these notes are valuable. About the Guitar Advertisement.
