2 Panels of vintage mail boxes

These are 2 full panels of mailboxes, they are not individual boxes. Most recently used in August 2011 before Hurricane Irene flooded our town and our post office closed. I am the deputy town clerk and one of the town commissioners. We are trying to find out what they might be worth and possibly sell them since the Post Office closed and left them. We have all the legal documentation to prove that it was left by the USPS for us to keep or sell. As you can see each panel has varied sizes of boxes. I can take a photo of the back side of the panels too, it that helps to see how they are fixtured.
