I'm renovating an old laundry room in my mobile home park in Arkansas. The facility hasn't been used in years (I just bought the property). I'm looking to get the place up and running again. I've got 4 stackable old Speedqueen Gas dryers with an old WEB decal on the front. Do these machines have any value? One of them works but the coin mech. has been disabled. I don't know anything about the other three. Any advice? Are they worth salvaging or taking to the dump? Thanks.
