I mentioned recently that I finally made a purchase on ebay last week. Here are those cards.
Unopened 1978s seem more plentiful than either 1977s or 1979s. Unlike unopened vintage packs, there is little temptation to open them since it is known who is included. The temptation got to me with the Kellogg's Upper Deck basketball packs and a few of the 1970 Kellogg's six-card packs.
Since I've yet to send anything in for grading, that didn't tempt me either. Have any of you opened a Kellogg's card to then send it in for grading?
