Is your question directed to all items or just one? Bottom pictures look like a broken pewter button. The other is another nice decorative, older button as well. The first item could be a decorative piece off of a jewelry box or something similar. What is it made of, how thick is it, and what does the end (hidden by your thumb) look like?
Hello and thanks for replyFirst item = Picture hook
Second item = Belt "concho"
Third item = Cant make out from pics... need side view and a few more close.
