"I'd add Woolrich & PKD to that, Heinlein as well, at least the earliest couple of stories for Heinlein & PKD." > Go to a pulp convention and ask that question. You'll gather 50 to 100 names that will bump up the price of a pulp.

''Do original stories by famous authors drive up prices?" Yes. You referred to SF authors. SF pulps with Asimov, Heinlein, etc stories sell at a premium. Non-SF pulps with Asimov, Heinlein, etc stories sell at a premium. [There was a 1950s issue of "Short Stories", I title I collect, that was very hard to find. It has a Robert Heinlein story. It took a few years, but I found a copy, filed, on purpose, in one of a dealer's SF pulp boxes.] ERB, OAK, REH, etc., big-name SF authors push up the price of the pulps with their stories. Sometimes the story in the pulp was re-written later on. So you need the pulp to read the original version. SF authors had letters published in SP pulps. Almost none of those letters are collected anywhere.

There are factors that determine the value/price of a pulp magazine; Condition,obviously. Age, the older the pulp, the scarcer it is. "Classic" Covers, the iconic covers, covers that sell a pulp regardless of the contents or authors Good Cover Art; not iconic, but attractive, or art by a cover artist whose work is collected. Contents, THE most important driver; for the majority of pulp collectors. Pulp collectors buy pulps to read! All Story; the 1912, October issue; the most expensive pulp. Why? #1: Author, Edger Rice Burroughs; #2 "Tarzan of the Apes [the complete novel]". Any pulp with an ERB story is priced much higher than mundane poulps of that title; and the same holds true for another 50 to 100 authors.
