The U.S. penny is 1.52 mm. (1.52mm/penny)(6.023x10^23pennies/mole)(1mole) = 9.15x10^23 mm for 1 mole of 1.52mm pennies. 9.15x10^20 meters

Convert to miles: 1 mile = 1.6x10^6 mm. That makes 2.6x10^13 miles for a mole of stacked U.S. pennies. It your stack only reaches 1.2x10^12 miles, you've got counterfeit pennies.
