I am holding my grandfather's homestead patents for two - 160 acre parcels of land in Idaho.

They were registered in 1903 and 1905. One parcel is on the St Joe River and the other on Lake Couer D'Alene. Looking at my grandfather's old photographs of the properties, it was rough going and quite likely that they simply left the property without selling it. I have no record that he had ever sold these lands, nor does my father.

Is there a potential present value to these do***ents other than historic?
