I am a little ways into a Dansco U.S. Type Set (first one). I guess that the majority of type collecting is done with an eye toward selecting the nicest affordable piece, which most of the time will mean one of the more common dates of a series. But to what extent would it be desirable to put together this album with the opposite intent, i.e., with either interesting varieties or rarer dates? It would take longer and be more expensive, at least if not compromising the grade levels too much. But such a theme would bring more interest to all levels of collectors when it's complete. A full 7070 is a thing of beauty even with the more available pieces. Just wondering how often this other approach might be employed by comparison.
