I find some of the stories of these non-pedigreed collections fascinating. E.g., the "Atlantic City" collection, which got a whole in-depth half-hour TV episode devoted to it.
But the problem is...it can be increasingly hard to find those stories, as time goes on. At least CGC & other sites give overviews of the current pedigrees; but for some of the non-pedigree collections, Google searches only point to threads like this, which don't actually tell (or at least link to) their background stories in detail.
Is there a site or a thread which does compile more of those stories?
