<p>Ben, take a look at the following link:<br>

While the link is dated in terms of street price, I would venture a guess and say that they're probably worth substantially more than 150 dollars starting price. As has already been mentioned, they are a pair of niche lenses, but they're still in demand for the right audience. I have an 8x10 camera and can say with certainty there is still a market for analog equipment, especially in the larger formats. My point is that I wouldn't "give" the lenses away, especially if they're clean examples. Patience is the name of the game for this type of equipment . . . </p>
