Imagine if you could time travel to the past just by rubbing the date on a penny! Ten year olds Joey (Johanna) and Eli can time travel to any year between 1859 and 1909, simply by rubbing a coin from a set of Indian Head pennies! Old Philadelphia can be a lot of fun. They see the first phone and climb up the arm of the Statue of Liberty at the 1876 Centennial Exhibition. They get to go on a sleigh ride through a Wissahickon winter wonderland. In between trips, Hal, proprietor of Hal’s Coins and Collectibles, teaches them tons of interesting facts about coins. However, their adventures take a serious turn when they wind up in a textile mill in Manayunk. They are shocked by the working conditions in the mill. They get mistaken for workers and are forced to work. They’ll be lucky if they don’t fall into the dangerous gears of the machines! Joey wants a friend more than anything. The fact that Eli is a super-smart history whiz should make him the ideal time travel partner. But Joey has a bad temper, and Eli has Aspergers Syndrome. Will their quirks drive them apart, or worse, get them stranded in the past forever?
