Today’s bills are small change
Since 1969, the $100 bill has been the largest bill issued by the government. However, it’s far from the largest denomination ever printed. From 1934 and 1935, the government printed a $100,000 Gold Certificate that was only used for transactions among Federal Reserve Banks.
Prior to 1969, the government issued $500, $1,000, $5,000 and $10,000 notes. Though they are still considered legal tender, the Bureau of Engraving and Printing expects that most are in the hands of private collectors.
