Anything wrong with screwdown holders?

[wfubob]

I believe most I've heard from say that they store cards either in penny sleeve/top loader, binders with top load pages, or CS Is/IIs (my preference, in pennys). What is the case against screw downs, if any? Is it the pressure against the cards? I have a few that have indentions the size of the '57+ cards, and I can see the obvious flaw with that one (if card isn't perfectly placed in the indention). But what about the flat ones?

Thanks,
Bob

I have never used them,but I heard people say that they had there cards
stick in them and ruin there cards.Not sure how true that is.

Speaking as someone with some knowledge of archival storage and display, my experience says avoid these holders, for two reasons:

1) A cardinal rule of displaying anything of value is you don't want anything touching the surface. This is why when you display a print or autographed photo or anything like that, you have a matte cut to fit around it, so the class or poly doesn't touch. To do otherwise risks precisely what you fear: the item sticking, and this is especially crucial for ballcards, where much of the value lies in the state of the surface. Lose that gloss, and the value takes a hit.

2) Plastic holders, while generally stable, are by their nature not chemically inert, since they are petroleum based. They may last a long time, and in fact we're not sure how long they'll last, but basic chemistry and the laws of entropy says they will break down eventually, and could possibly react with the item! So unless you're using glass, which IS chemically inert (since it is comprised of one compound: silica), you're not completely safe against an adverse chemical reaction.

TPG holders like PSA and SGC,you will note, take care not to touch the surfaces of the card, but rather grip the edges, and keep a space between it and the plastic. So in that regard, they are a wiser option, depending on the value and condition of your cards.

I do not use them but did have a bad experience with one. While working on the Topps 1974 Deckle set in white back I bought a Luzinski from a reputable seller that was encased in one ( he had obtained it that way). I display all my sets in binders so set to free it from the slab. It unscrewed easy enough but the card was stuck to the bottom layer of the plastic and could not be removed without damage to the back of the card.

I have used them since the eighties and never had a single problem.

If there is a little dirt or grit on the surface you will drive it into the card. I did that with one. I also created a fine network of creases with a larger holder on an Exhibit card. My advice is don't do it.
