I am 3 years late to watch this video, but such a good button video. This inspires me to sit home during this corona-virus pandemic and make my own buttons. LOL
You have stumbled upon some of the most desirable antique and vintage buttons assembled. Some of those are worth hundreds and even some worth over $1000. I enjoyed your enthusiasm and was impressed with your knowledge of techniques and history. If you want to know more about vintage and collectable buttons, check out the National Button Society's website. Chances are good that there is also State Button Society where you live. If that's not enough, there are local clubs you can join to get hands on knowledge!
