Money is filthy. Depending on which study you read, the level of grossness may vary, but all researchers seem to agree — paper money is just straight up nasty.
Take this 2012 study from the Queen Mary University of London, for example. Researchers found 8 percent of credit cards and 6 percent of paper money had as much bacteria as the inside of a dirty toilet bowl.
More recently, researchers at New York University's Dirty Money Project analyzed genetic material on $1 bills. They identified some 3,000 types of bacteria, but the number of bacteria on the bills was actually higher — because a handful of the microorganisms hadn't been cataloged yet.
