Dash Heater/AC Control Panels WIW

[71vert340]

 Found these in my shop today buried under stuff. The back control panel in the photo is for a ribbed 70 non-AC dash. The middle one is a ribbed 70 AC panel. Vanes and air shut off work. The front one is a 71 and newer rallye Ac dash panel and all vanes etc. work. What are they reasonably worth to a buyer?
