Charlie's right about its rarity - outside of the Coin World library in Sidney, OH (and perhaps the ANA library in Colorado Springs), I don't know where to find a complete set.

My memory may be flawed on this, but I remember doing some research years ago that required access to old Coin World articles. As I recall, Coin World is available on Microfilm or Microfiche at the American Numismatic Society. I believe the company was University Microfilms. I would assume Amos Press also has a photographic copy at their offices in Sidney, OH.

I am sorry to say that I cannot remember the name of either one, but I have known two collectors who as of a few years ago had complete sets of Coin World. Only subscribers to a collector's newspaper would collect so many. I think that the comments in The E-Sylum might well unearth some sets.

When Frank Katen sold my library, he reluctantly put in my complete set of Coin World, lots 404 to 420. It sold as a complete set as lot 420A at $300-- I think it brought the highest price of any item in the sale of November 27-28, 1971. Of course, it only covered up to 1969 because of the 1971 offering date.
