WASHINGTON (10/5/10)--Production problems at the Bureau of Engraving and Printing have pushed back the issue date of the new $100 bill, the Federal Reserve (Fed) announced last week. The new bill was scheduled to be issued on Feb. 11. The Fed has not established a new issue date. According to the Fed, the Bureau of Engraving and Printing has identified “sporadic creasing of the paper” during the printing of the bill. “As a consequence, the Federal Reserve will not have sufficient inventories to begin distributing the new $100 notes as planned,” the Fed added. The bill design combines the usual portrait of Ben Franklin, and some previously added security enhancements, with a pair of brand new, advanced counterfeit-deterrent security features. The bill also features a blue three-dimensional security ribbon and an interpretation of the classic liberty bell image which, when tilted, changes colors from copper to green, making the bell appear to disappear and reappear in an inkwell. The new security features were researched and developed for more than a decade, according to U.S. Treasurer Rosie Rios. For the Fed release, use the resource link.
