Protecting your cards

I prefer polypropylene (I check my penny sleeves and binder sheets are made of this before purchasing, typically they are).

Humidity is a different issue. I would recommend a temperature controlled space - no basements or attics. Keeping the humidity within a certain range probably isn't feasible, but my theory is if you're comfortable, the cards are probably fine.

No toploader made in the 21st century by a reputable supplier contains PVC. That stuff was hobby headline news in the 1980’s, if not before. Even if they did, the chances that such toploaders would noticeably damage your cards in your lifetime is all but nil.

I think the Mylar thing for the garden variety collector is largely unnecessary. Yes, it is the most "inert" material, but realize that the HOF uses Mylar because they need the cards in their collection to last for hundreds / thousands of years more, not just the next 50-75. I mean I enjoy the idea of my collection outliving me and serving generations to come, but in reality I'm going to be fertilizer in all likelihood 50 years from now - so why do I really care? Polypropylene products and the other stuff that penny sleeves, toploaders, Card Savers, and One Touches are made of is also "inert" and "archival", even if they don't pass the same rigorous tests that Mylar does. The one time I tried to use Mylar, I found it very rigid and difficult - and I will agree with the previous poster who said it doesn't work well with toploaders. My cards looked great when finally IN the Mylar, but good luck getting them in or back out. Not for me.

Not true. It's the SLEEVES that are PVC free.

Ok, I stand corrected - but hear me out: The problem in the 80's with PVC was the plastic pages (soft sleeves) that had PVC. Right? Toploaders I don't think were ever really questioned because the PVC in them acts differently / takes longer to break down?

Pretty sure the concern was the pages that were prevalent back then. I think the reason toploaders may not be concerning is that they aren't directly in contact with the card if you use a sleeve?

Toploaders might have PVC, but I think at this stage in the game if they were regularly damaging cards - we would know about it by now.

I should think so.
