The Federal Reserve does not sell precious metal coins or bullion. You may request the newly minted coins and state quarters from your local financial institution. Additionally, the U.S. Mint sells special collector sets of the state coins. Start by asking your bank if it provides foreign exchange services. Some main offices of larger banks have a foreign exchange teller.
Some airports have foreign exchange desks.
Foreign exchange services are not available at Federal Reserve Banks. The Federal Reserve Bank of New York posts rates of frequently traded currencies twice a day. They also appear in the Wall Street Journal and the business section of many local newspapers. The Wall Street Journal publishes weekly rates of all currencies under the table heading World Value of the Dollar in its Monday edition. A complete set of FAQs on currency and coin is available from the national web site for Federal Reserve Bank Financial Services.
