My remark was kind of a knee-jerk reaction to what seemed like the beginning of yet another bash-Jabo-devaluing-collections-ruining-the-hobby-type thread. That's what it sounded like. And we've had quite a bit of that lately.
No, I don't remember cullet / booboos being discussed before.
I think the topic of "wastage" in the special runs is a valid one for those who buy marbles primarily for an investment, or those who are more business-oriented than others. I personally am one of the Others. My only concern is do I want a particular marble, or not? I have my own standards (pretty high) for beauty, rarity, condition, interesting-ness, and whatnot, and I spend what little money I have carefully. If you can call buying marbles "spending carefully!" And I cull my own herd, constantly. So "the overall quality of marbles being sold to collectors" is not a concern of mine, because as a collector I don't have to buy any of them.
And I have never ever been accused of being business oriented. Which is why I'm going to be spending my declining years in a cardboard box. Surrounded by marbles. And toy horses made before 1960. And cat food. Hopefully, in the Florida Keys. Although I hear Trinidad and Tobago is cheap, and south of the hurricane zone . . .
