Q: I have one antique andiron from a set that belonged to my great-aunt, who was the niece of John Deere, the founder of the tractor company. Would one andiron be worth half as much as a pair?

A: Unfortunately, a single andiron would sell for considerably less than half the price of a pair. Even if a collector did not want to use the andiron, one does not display as well as two. And John Deere’s fame, in this case, is of no help.
