Generally speaking, it is my opionion, the lowest grade of most products, whether 1911s, rifles, cars, boats etc... loose the most % of value the fastest. As time passes the market for the lower quality dissappears and only the high quality ones retain some market value. Of course there are bound to be exceptions.
As the old saying goes " The race is not always won by the swift, or the battle by the strong. But that's how the smart money goes."
Experience is a very bad teacher because it first gives you the test and then teaches you the lesson.
