The average $20 bill is in circulation for 7.7 years, according to a report by the Federal Reserve. That’s better than the $10 bill, which has a life span of only 4.2 years, but worse than the $100 bill, which is in circulation for 15.0 years.¹
Here’s a quick look at what goes into creating a $20 bill and what determines when a bill’s lifespan ends.
A $20 bill starts out life as part of a big, blank sheet or paper – but not just any paper. While most paper is made primarily from wood pulp, the paper used by the U.S. Bureau of Engraving and Printing doesn’t contain any wood at all. Currency paper is composed of a special bland of 75% cotton and 25% linen. It’s made with special watermarks and has tiny blue and red fibers embedded in it along with a special security thread.²⁺³
Each blank sheet is tracked from the time if leaves the mill unit it is printed, and the entire shipment is continuously reconciled to make certain all are accounted for.⁴
These blank sheets of cotton and linen paper get printed four times.
Background images and colors are printed – both sides at once – using offset presses that are over 50 feet long and weigh over 70 tons. After drying for 72 hours, the portraits, vignettes, scrollwork, numerals, and letters are printed on the back using Intaglio presses that are a mere 40 feet long and weigh only 50 tons. After drying for another 72 hours – in special guarded cages – more portraits, vignettes, scrollwork, numerals, and letters are printed on the front side using the Intaglio presses. Finally, the serial numbers, Federal Reserve seal, Treasury Department seal, and Federal Reserve identification numbers are printed using a letter press.⁵
Cutting and Wrapping
Once dry, these printed sheets are gathered in stacks of 100 to be cut by a specially designed guillotine cutter. Each new stack of 100 $20 is wrapped with a special paper band. Ten of these 100-note stacks are gathered, machine counted, and shrink-wrapped into a bundle. Then four of these shrink-wrapped bundles are collated together, given a special bar-code label, and shrink-wrapped again to create a brink of 4,000 bills, worth $80,000.⁶
Distribution and Circulation
The Treasury Department ships these newly printed $20 bills to the Federal Reserve Banks, who in turn pay them out to backs and savings and loans – primarily in exchange for old, worn-out bills. The new bills are handed out to customers of these institutions as they withdraw cash, either through tellers or through automated teller machines.⁷
The average $20 bill will change hands often, but even the U.S. Bureau of Engraving and Printing isn’t sure how many times a bill will move from one pocket to the next. Contrary to popular believe, the government doesn’t have any way to track individual bills.
There is a polyester security thread embedded in the paper that runs vertically up one side of each bill. If you look closely, the initials USA along with the bill’s demonization and a small flag are visible along the thread from both sides of the bill. This thread makes currency more difficult to counterfeit, but cannot be tracked electronically.⁸
Banks gather worn out and damaged currency, sending it to the Federal Reserve in exchange for new bills. The Federal Reserve then sorts through these bills to determine which are still usable and which are not. Those bills deemed usable are stored until they can go out again through the commercial banking system. Those deemed no longer usable are cut into confetti-like shreds. Most are then disposed of; a small portion is sold in five-pound bags through the Treasury’s website.⁹⁺¹⁰
