The Columbia series is well known for many poorly repunched dies and doubled hubs. They are also know for over using dies, many of the terminal state dies show numerous serios cracks. As far as I know, there is no comprehensive catalog of the varieties and right now they do not command much of a premium.
I always pull these from junk boxes and accumulations whenever I see them.
