1939 Lincoln 4-door value

[Cool Hand Lurker]

A friend of mine died recently and left two Lincoln Zyphers in the garage that the widow wants to sell. They were his Grandfather's cars. I saw them about 50 years ago and they were solid and complete and are still parked in the same garage now. I suggested a well known auctioneer but they have not responded back to her. I have a good idea what Model A's and mid-forty coupes are worth, but I am in the dark on the Lincolns. Anybody know a lot about these cars and their values?
