DON'T OPEN THEM! At least if you are planning on selling them. Let the unopened material people gamble on possible 10's. Take the premium you will make selling into the unopened market and purchase the cards you want directly with the money.

Topps first factory set was exclusively in the J.C. Penney catalog in 1974.

I read that, too. Additionally, I read that Topps did not release any other factory sets until 1982. The OP should post pics of the sets of which he spake.
