Q:I just went to a garage sale and found three cast-iron toys that are replicas of very old Case farm equipment. I bought a steam tractor, a threshing machine and a water wagon. They have almost perfect original paint. How much are they worth?

A:There were a number of companies making models like this in the 1970s, although they represent machinery used in the late 1800s and early 1900s. The almost perfect condition suggests a 1970s rather than an 1890s origin. Value of each: under $50.
