About The MCF

The first ever Mercer County Fair was held for only one day, on October 28, 1852. The entrance fee was 25 cents for anyone twenty-one years of age and older. The competition was very light, but they still didn’t make enough money to pay all the premiums and expenses. Three more poorly supported Fairs took place, and then none was held for twelve years because of lack of interest and lack of support.
