What is the Largest Denomination of U.S. Currency?

By GovMint :

The largest denomination of U.S. currency currently in circulation is the $100 bill that famously features Benjamin Franklin.

Historically, however, the U.S. issued much larger denominations of currency. The highest was the $100,000 bill that featured a portrait of Woodrow Wilson, though they never circulated among the general public and were used exclusively for Federal Reserve Bank transactions. Other large denominations included the $500, $1,000, $5,000, and $10,000 bills, which were last printed in 1945, and officially discontinued in 1969.
