I sold a set for $125 a couple years ago, plus $80 in shipping. They are typical large FSJ parts. If you are trying to sell it actively, no one needs them or is willing to buy one. If someone "needs" it, they are impossible to find and you pay a mint for them.
Also, a general rule of FSJ parts: the bigger it is, the more expensive it is to ship, the bigger the PITA to package=the farther the person that wants it is. Since you are in South Dakota, most potential buyers will be in Florida, Georgia, or Maine.
