I have some rare military collectibles are they worth anything?

My family inherited a congressional medal given for his pioneering in polar exploration for his part of the "Byrd Exploration of 1930." It is 18 kt gold. And a photo album with approximately 150-200 pictures of the expedition. I am wondering if these are worth any monetary value to a collector or a museum? I have tried to research but came up with nothing, any help would be appreciated.
