"The website, H.I.P. Pocket Change (History in Your Pocket) is a government website where kids can learn all about the United States Mint. The site is all about fun and information, especially coin information. According to their website, “It all started in 1997, when President Clinton asked federal agencies to find resources that could "enrich the Internet as a tool for teaching and learning." The result was a pooling of hundreds of free educational treasures that can be accessed by kids, parents and educators. "
