Stamps that I found

I came across this Old collection of Stamps down in a old ghost town called Hazelton Springs, Missouri. The man that started this collection passed away about 20-30 years ago, and his wife had them packed away but when she have to move to california recently she gave me all the items she was not able to take with her. I am very proud to have found this album of stamps because the property was sold and they dozed everything, I wish i would have time to get alot more items out there was alot of rare items & books. I would like to know how much this collection might be worth ofcourse, and if anyone can tell me alittle more about these stamps would be very helpful so feel free to leave me a comment thanks, Jimmy
