Here is My Stamp Collection, Can You ID Them?

As the title states and referring to my last blog here are some pictures of a small portion of the collection I got for a mere $10 at my local Thrift Store. Can anyone help identify some of these or know what they are? When are they from and are they rare or in demand? How is the collector stamp market anyway? I have no idea. Maybe you do. Rewards to the most helpful people especially if you buy any off me with STEEM. Hoping to move the entire collection.
