The $1,000 bill featured Grover Cleveland on the obverse and the words “One Thousand Dollars” on the reverse. It was printed as a small-size Federal Reserve Note in 1918, 1934 and 1934A, and a small-size Gold Certificate in 1928 and 1934.

Federal Reserve notes are a blend of 25 percent linen and 75 percent cotton. Currency paper has tiny red and blue synthetic fibers of various lengths evenly distributed throughout the paper.

In 1934, the $100,000 Gold Certificate became the highest denomination ever issued. It was never intended for public use. Instead, it was meant solely for official transactions between Federal Reserve Banks.
