United States Twenty-Dollar Bill

The United States twenty-dollar bill ($20) is a denomination of United States currency. U.S. President Andrew Jackson is currently featured on the front side of the bill, while the White House is featured on the reverse side, which is why the twenty-dollar bill is often called a "Jackson".

The twenty-dollar bill in the past was referred to as a "double-sawbuck" because it is twice the value of a ten-dollar bill, which was nicknamed a "sawbuck" due to the resemblance the Roman numeral for ten (X) bears to the legs of a sawbuck, although this usage is far less common today than it was in the early 20th century. The twenty dollar gold coin was known as a "double eagle". Rather than a nickname, this nomclemature was specified by an act of congress.

The twenty-dollar bill is the primary banknote (and in most cases, the only banknote, as it would increase costs to make ATMs compatible with other bills) dispensed by ATMs in the United States as well as the primary bill used for withdrawals or cashing checks. It is, therefore, the highest denomination note most commonly used by Americans on an everyday basis.
