Brian-- I guess Yahoo does not want you you to know about those coins
Yesterday the link went straight through but today I see the Yahoo notice. However, when I clicked on "yes" I want to proceed the articles come up.... and nothing bad happened when I did. They are from SCD and discuss the 64 and 71 coins. If you do not want to enter The Forbidden Zone, type in internet search for "SCD Topps 1964 coins". The articles will be more informative than memory
Edited... Click on "here", and the second article is Sports Collectors Daily so second search should substitute that for SCD
By the way I have of all the Topps coin sets through 1994, including the 56 Pins. Not sure if there were others after 1994
