Charles Q. asks: Has a $1,000,000 single bill ever been printed? And if so, what would such a bill be worth to a collector?
The highest denomination note ever printed in the United States is the 1934 $100,000 gold certificate. This note was not meant for general circulation but for transactions between Federal Reserve Banks. None are available to collectors, though the Bureau of Engraving and Printing displays a spectacular sheet of these notes at many major coin shows.
