Serious question: did that old school collector give me bad advice about bagging comics?
Back in March at a convention in Cleveland, this guy who's been collecting since the 70s told me to never use Mylar bags for silver age books. Said they trap moisture and ruin the spine over time. I listened to him and kept everything in standard poly bags. Now two of my keys from the early 60s have that weird acid migration staining on the back covers. Should I have gone with Mylar anyway? Anyone else get advice from a veteran collector that backfired?

So did that poly bag actually cause the damage or was it something else?

March 7th was when I switched all my 60s books to Mylar after a buddy who runs a shop told me poly bags are basically garbage for long term storage. That acid stain you're seeing is the poly breaking down, not Mylar trapping moisture. I've got books in Mylar going on 15 years with zero spine issues.
