Oakwood Country Club, located in Coal Valley, was host of the Hardee's Golf Classic from 1986 through 1994. The tournament was later renamed to "John Deere Classic" once sponsorship was taken over by Deere & Company. Now the tournament is hosted at the TPC at Deere Run course in Silvis, Illinois.
In the 1800s, Coal Valley originated as a small village. The purpose of the town was to mine coal, hence the name Coal Valley. Also, they mined here because the ground is abundant with coal. Eventually when coal mining halted, Coal Valley became what it is known today.
