Well, I guess you could call me a type collector in the sense that I decided some time ago that for financial reasons set collecting on prewar wasn't realistic for me but I still wanted to play, so I decided to get a few examples that I really enjoy from the prewar sets I like. In some cases I just kept the cards I already had accumulated.
I usually prefer to get a popular or HOF player over a common, all other things being equal. Just not that interested in having a card of No-Names in my collection.
My Lefty O'Doul collection has become a type collection of sorts since he is in many sets of the 1930s and many PCL sets that I otherwise have no interest in collecting.
