The Treasury Note (also known as a Coin Note) was a type of representative money issued by the United States government from 1890 until 1893 under authority of the Sherman Silver Purchase Act in denominations of $1, $2, $5, $10, $20, $50, $100 and $1,000. It was issued in two series: an 1890 series with $1, $2, $5, $10, $20, $100 and $1,000 denominations, and an 1891 series that added the $50 denomination. A $500 note was designed but never issued.
