Of all items that are counterfeited, money is the most common. Despite the myriad protections against counterfeiting found on U.S. currency, many people believe they can get away with passing fraudulent bills.
Counterfeiting money is a form of fraud that is prosecuted aggressively by the government. Having fake money in the supply cuts into the integrity of authentic bills and purchases made with them are essentially stolen.
As such, the punishments for counterfeiting are severe. Captured counterfeiters can spend up to 15 years in prison, have their tools confiscated, and will likely also have punitive fines.
There are many ways to determine whether money is counterfeit. One of the biggest giveaways is that the counterfeits most often will not use the right kind of paper, causing their fake bills to feel like crude copies rather than legal tender.
