100 years, you do not have to look that far. Those of us on the top end of current antique buyers are dropping off every year. Young people see guns as functional tools. As the I-Phone Babies grow, they are not going to develop a love for the Old West and it's artifacts that they were never exposed to in the media and social experience. I-Phones, computers, social media, they do not care what happened in the past, they are only concerned and interested in the present and the future. Antique/historical guns will go back to what they were 70+ years ago, or less. A product for a small niche group of hobbyists. There will be the same number of old Colts and Winchesters, but far fewer people interested. Same supply, less demand, prices will plummet. Wait a generation or two, you will find me prophetic. Of course most of us will not see that, just like the few collectors 70+ years ago could never imagine what antique Colts and Winchesters are selling for now.
