Anthony N.The one on ebay last nite was the first one to be offered there in the last 5 years that I've been tracking packs. Previous to that there were 2 in Memory Lane (assuming it's a different pack) and there was one at the National in Cleveland in '04, that sold in a hour on set up day.
As stated, the value is not in the card contained but rather in the rarity of a legitimately unopened pack. Opening that pack (especially on a 1 card penny pack like this, where you can probably tell who is contained therein) would immediately cause a huge loss of value.
From what I understand there was a find of unopened Sport Kings packs about 15 years ago, which is probably why wrappers are so easily found and inexpensive. For the pack collector Sport Kings are about the earliest pack likely to be found that was marketed for the sole purpose of selling cards, and as such is the logical starting point for such a collection.
edited for grammar.
