In the history of collecting there have been certain sets that haven't quite hit the mark.
In a word, I would call them "defective."
Now, let's define "defective."
I am not using "defective" to describe a concept. There are plenty of sets with flawed concepts. 2008 Documentary, 1997-98 Pinnacle Inside (cards in a can), 2009 Yankee Stadium Legacy. There are also plenty of sets with flawed marketing strategies. 1982 Kmart, for example.
But those don't describe the actual card.
There are some sets in which the cards in the set simply don't work. They don't operate properly. They're dysfunctional. It's possible that some of these sets have flawed concepts or marketing strategies, too, but the majority of frustration comes when the collector handles the actual card.
I came up a list of eight or nine defective sets. This is a list of only sets that I know. There may be other sets that are more defective. But I'm either unaware of them, or nobody is paying me any money to conduct exhaustive, time-consuming research to find them.
From those 8 or 9 sets, I whittled it down to six sets.
Because it fits my vacation schedule.
Again, no cash inflow for this.
I will be counting down the most defective sets, one per day.
See if your favorite defect is on the list!
Here is No. 6:
TMDSIK: 1970-78 KELLOGG'S
I think everyone knows by now that I love Kellogg's 3-D SuperStars card with all my heart.
In my eyes, they are almost a perfect card.
The sad reality is they're not perfect.
1970s Kellogg's cards tend to crack. If you're not careful with them, the lenticular coating -- or whatever the hell it is -- wears down and you're left with all sorts of ugly lines on your beautiful Kellogg's card.
The worst part is, you can be as careful as possible -- barely even touching the cards for years -- and then one day you'll look in a binder and you'll see cracks in your Kellogg's card. It's very mysterious and very aggravating.
After 1978, Kellogg's went to narrower cards for a couple of years. I have noticed that none of the cards I have for 1979 and 1980 have any cracks. I don't know if the wider width promoted cracking, but the vast majority of cracks I've seen have occurred in 1970-78 cards. (I have seen cracks in '83 Kellogg's, which are also very thin, so this theory isn't perfect).
This doesn't mean I dislike my cracked Kellogg's card or '70s 3-D Xograph technology in general.
It just makes me sad enough to put Kellogg's as No. 6 on the Most Defective list.
