Need help assessing the value of some Luger pistols
 

My uncle gave me a collection of seven Luger pistols and I need help assessing their value. Does anybody know of a good book or website that could help me out? Is there anybody near So. Oregon that could take a look at them and help determine a value? Any information would be appreciated.
