“The BEP prints billions of dollars – referred to as Federal Reserve notes – each year for delivery to the Federal Reserve System. The Federal Reserve operates as the nation's central bank and serves to ensure that adequate amounts of currency and coin are in circulation. The BEP does not produce coins – all U.S. coinage is minted by the United States Mint. The BEP also advises other federal agencies on document security matters.” https://www.bep.gov/about-bep
