More on currency

More on American currency since 1861 from the Federal Reserve Bank of San Francisco's American Curreny Exhibit:

Federal Reserve notes are the only U.S. currency issued today. Federal Reserve notes were initially issued in denominations ranging from $5 to $10,000. The $100 note has been the largest denomination printed since 1946. In 1969, all notes greater than $100 were retired because of declining demand.

The design of Federal Reserve notes has changed some over the years. In 1929, the size of the notes was reduced. It also was decided that all currency would have a portrait on the front. Denominations under $100 would have buildings or monuments on the back. The inscription "In God We Trust" was added in 1955.
