Nice handful of old buttons. What is the item under the shed? Looks a little like a CW saddle shield.
Some nice finds there. This button in particular is known as a Jacksonian button. They were popular around the time that Andrew Jackson was president and are distinguished by the wide rim with some type of motif in the center. Here is a picture of some of the variations that are out there.
