As an addendum to this thread, last night I found the following article from the November 1, 1976 Sports Collectors News, with an update from Jim Beckett on how his price survey was going and the feedback he was receiving. Sorry for the crappy photo quality, but I think the article should be legible. It's interesting that Beckett emphasized that he was not going to sell the survey results, but would make them freely available to the hobby. Obviously that changed as his price surveys grew way beyond what he must have imagined in 1976.
