I shared Dr. Jim Beckett’s first price survey results a few weeks ago. Well, the following year, he kicked off an update with the following bit of hobby history that I scanned from the January 1978 issue of The Trader Speaks: Dr. Jim Beckett’s Price Survey Update!
David Kathman on the net54 boards pointed out that SCD published the 1978 survey update results in their July 15, 1978, issue, with an abbreviated version in the 1978 edition of the Sport Americana Baseball Card Checklist book. I believe The Trader Speaks published the updated results in their April 1978 issue; I just don’t happen to have that one in the Hobby Library to be able to include a scan.
Then, in 1979, Beckett’s first price guide book, The 1979 Sport Americana Baseball Card Price Guide, was published with the help of Dennis Eckes.
The rest is history!
