I don't know what the back looks like but if that reads McCormick 1831 on the front.I would say that it is probably something to honor CYRUS HALL McCORMICK who invented the reaper.Here is a pic of a centennial coin that I have.
Nice 1910! earliest penny I dug up is 1913! I also got something from chicago. A chicagos world fair token! oops i did find an older date penny but was an indian one.
