We recovered an 1836 American penny with three holes pierced in it at the American  Millwright's House at Mill Creek State Historic Park (4 miles outside Mackinaw City, Michigan).  The house dates to roughly 1820-1840.  Numerous trade goods were found at the house, and there was a large metis population in the area at the time.
