hank you for your recent correspondence to the Federal Reserve Board regarding Federal Reserve notes. Because of the nature of your question, you may be interested in our Frequently Asked Questions about currency and coin:
http://www.federalreserve.gov/faqs/currency-coin.htm
You may also be interested in the Federal Reserve Bank of Philadephia's online publication, "Symbols on American Money," which can be found at

As for your question about credit unions, please know the Federal Reserve supervises only state-chartered banks that are members of the Federal Reserve System. The National Credit Union Administration (NCUA) is the agency that supervises and regulates federal credit unions.
I hope this information is helpful.
Sincerely,
LOD
Board Staff
