It is estimated by the U.S. Secret Service, the federal agency responsible for protecting the U.S. currency, that prior to the adoption of a national currency in 1863 up to one-third of the currency in circulation was counterfeit.¹
Today, while 90 percent of all known counterfeit currency is seized before it reaches circulation, combating counterfeiting remains core to preserving the integrity of the nation's money.²
Money Matters
The advent of high-tech printers and inks continues to raise the bar on what the federal government has needed to do to limit counterfeiting, leading to a range of new strategies.
To make U.S. paper currency more difficult to copy, there have been continual changes to the artwork, paper and ink. Summarized below are some of these recent changes.
- Portrait—The portrait has become much more sophisticated by becoming closer to a life-like picture than the screen-like background it was previously. On counterfeit bills, the portraits often appear to be unclear or unnaturally white.
- Border—The border design is now composed of intricate, crisscrossing lines that are clear and unbroken, distinguishing them from the smudged or broken lines of counterfeit bills.
- Paper—The paper is now embedded with tiny red and blue fibers. A polyester thread is also woven inside $10, $20, $50 and $100 bills with "USA TEN," or "USA TWENTY" printed on it to match the denomination. This makes it nearly impossible for photocopiers to reproduce.
- Ink—The ink used is a special, "never-dry" ink that can be rubbed off. This is not foolproof, however, since ink on some counterfeit bills can be rubbed off as well.
- Microprinting—Surrounding the portrait are the words "The United States of America" in miniature letters. It appears to be a black line to the naked eye, and is how a photocopier would reproduce it.
Keep in mind that you are not reimbursed for any counterfeit currency that may come into your possession. So you are advised to be careful about the large bills you accept for payment.
