Toploaders vs. one screw screwdowns
 

I have bought a few ungraded modern cards and am inclined to keep them that way. I like the look of the one-screw screwdown holders (recessed) better than the old standby toploader and penny sleeve, but are these safe for long-term storage, could the plastic eventually adhere to the card? even though the area for the card is recessed? Thanks.

I think they should be fine. They don't press on the card so there shouldn't be any sticking problems. At least as long as you get the right thickness, there are ones with deeper recesses for cards with bits of supposedly used clothing and equipment in them. I've used a couple of those for Old Judges with a home made insert to get the size right.

Personally, I doubt they would stick as no part of the slab, as far as I know, puts any type of pressure on the card.

I use recessed screw downs and see no problems with them. Others seem to prefer the magnetized one instead. No one seems to like the non recessed screwdowns though.
