Micah,
That's quite a bunch of guns! The earliest I see, unless I've overlooked something is the Miquelet (sp). Then come what appear to be, some originals. I can't make out what the lever gun is. And then of course several early "customs". I am partial to the half stock with the wrist repair. I don't know what your circumstances are, or what is being asked, but I would research the makers that are known on line or through whatever resources you have available. To ask for opinions and values based on the pictures you have posted is a tall order that may do you more harm than good. Good luck, there may just be some hidden treasure on those racks.
