Free printable play money can be found on websites such as Printableplaymoney.net and Hadtoknow.com. The kinds of play money offered range from unrealistic money in various colors, to more realistic money and money that allows the user to replace the president's face with a picture of her own choosing.
The website Printableplaymoney.net has the larger selection of the two. It includes many types of money, ranging from realistic to unrealistic and colorful. It also has a download available for coins that people can print out. However, not all of the currency has the back of the bill available to print. Hadtoknow.com does have the front and backs of money available, but it does not have as big of a selection as Printableplaymoney.net.
