"I believe the older SAAs will continue to rise...."
We'll see. There's a school of thought which holds that when the Boomer generation that grew up watching B Westerns and television Westerns starts dying off SAAs will decline in value, or anyway not continue to increase. Because of the size of the Boomer generation relative to the succeeding generation or two, investments and collectibles of all kinds will decline in relative(inflation-adjusted) value according to that school.
