Back of bill: Independence Hall, in Philadelphia.

$100 notes and bills have at times carried images of George Washington, Abraham Lincoln, Senator Thomas Hart Benton, and President James Monroe. Benjamin Franklin has been on the bill since 1929.

The first modern era anti-counterfeiting measures were introduced under the 1990 series with microscopic printing around Franklin’s portrait and a metallic security strip on the left side of the bill.

In 1996 the bill underwent a major redesign (again to combat counterfeiting), which included a watermark of Franklin to the right side of the bill, ink that changed from green to black when viewed at different angles, a higher quality and enlarged portrait of Franklin, and hard-to-reproduce fine line printing around Franklin’s portrait and Independence Hall.
