I think it varies greatly depending on which era you're referring to. The Edgar Church collection I was discussing dated between roughly 1937 to 1957. As far as I know, the back issues he purchased were from those early days in his collecting. I wouldn't think there would be many places to acquire back issues in 1937, certainly not like there would be say from the 70s forward. Also, in regard to the Church collection, the back issues he bought looked to be very recent back issues, I'd guess within a year of them being on the newsstands. Those back issues were stored the same way as the comics he purchased new and over the decades that they were stored, their state of preservation was essentially the same as his new comics. In short, the fact that they were purchased second hand, likely only a few months after publication, doesn't seem to negatively impact their value much, unless significant defects are present. It's also worth mentioning that any secondhand comics he purchased were only a tiny fraction of his overall collection. When it comes to Silver Age on forward, I doubt there'd be any way to know if the original owner filled in any missed issues after the fact. If that detail is monumentally important to a skeptical collector, then maybe pedigree comics aren't their best option. I've known collectors who LOVE pedigrees and the back stories that go with them. I've known collectors who essentially balked at pedigrees, not caring at ALL who previously owned them or how they came to survive. Then there are people in the middle who just want high-grade comics and if it's a pedigree, that's fine with them, but they don't seek them out. There are SO many ways to collect ...

I'm by no means an expert on that collection, but I do remember hearing that the stamp stops at a certain point in the collection and that the collection goes beyond that stoppage. Hopefully, someone more knowledgeable about this collection will chime in and provide more details about when that store stamp stops.

Oh no, such sad news. I never met her but had heard about from fellow collectors, one of which was on the same path of building a complete DC library. RIP dear lady.
