I though it would be easy enough to use the 2x2 self adhesive cardboard holders. Place the coin on the non-adhesive side, peel of the paper, fold over, you're done. Problem is making sure the coin doesn't move at all when flipping it closed, or it goes in the sticky stuff.
I'm thinking these holders are a bad idea. Thoughts?

I have never used them personally, but I know some people believe that the adhesive can be bad for coins. Over the years the adhesive could have some possible negative effects. The self adhesion sounds nice at first, but overall I don't think they are much more convenient (if at all)and not knowing about the long term safety of the adhesive was a turn-off for me. I am sure others who know more about them will chime in. I find it easier to use flat clinch staples for my 2X2 holders.

I just bought a flat clinch stapler at lunchtime :-) Rapid S17. Works very well.

I've also heard from people that used to use them that after long term use that the adhesive fails and they ended up having to staple them shut anyways.

Ive never used them but have bought a Franklin proof that was in one and left a sticky spot on the edge of the coin, I brought it back to the dealer and he gave me $5 off the original price

Adhesives will usually migrate, I wouldn't use any adhesive near anything of value. Adhesive will eventually get on it.

I don't trust 2x2's. I don not know why, I just don't.

I never used the sticky ones, but I would stay away from the stapled kind for long time storage. I just helped a friend with an inherited coin collection that included some beautiful BU Morgans. The staples had crroded/deteroiated and discolored the coins. |

The big thing with staples is humidity. If they are in an area where its warm and moist, they will corrode. I have all mine in 2x2's with staples but am thinking of moving them to more suitable storage.

Staples scratch. I have several in my personal collection that have been ruined by a staple from the coin in front of it. I have seen lots in dealer stock with the tell tale ruin too.

I recently made some discoveries on the staples. Yep, they scratch coins. But far more often, they tear the plastic off of the 2X2 next to them. I still haven't gotten a clinching stapler, but I spent a LOT of time using a needle nose pliers clinching the staples in all my older stored coins. In fact, the pliers are a new part of my routine, put all coins in 2X2's, clinch the staples, sort, label, store. In that order.

 If you have a fold flat stapler or crimp them with pliers, then the staples are of little concern. Of course, a significant number of collectors do not spend the money on a quality stapler or take the time to crimp, just like some show dealers still use PVC flips  As for the adhesive 2x2s, I do not personally object to them but I have found that the adhesive loses its grip after a few years on some. I like the standard 2x2s because they can be reused. I have had some of my coins in 2x2s for over 25 years and they are still in perfectly fine condition, the ambient storage conditions will affect coins the most. Edited by biokemist6

As far as the adhesive 2x2's go, I don't trust them. I can be a bit clumsy, and just know I'd glue one of my coins.
I do use the staple type, and find no problem if I take a needle-nose and clinch the ends of the staples. I've learned to staple on the outer edge of the 2x2, as far from the coin as I can. I also, when taking a coin out of a 2x2, remove the staples completely first, removing any scratching damage possibility.

I've never used them. All of my 2x2's are the staple type. I have gotten very adept at using a small craft hammer to flatten the staples out. I've never hit a coin. Would love to have a flat clinch stapler, that is definitely the way to go. I've only ever scratched one coin and that was before I knew any better and didn't flatten the staples. I too would be afraid the adhesive ones wouldn't last and was afraid the coins might start falling out of them also. That's just my fear and not my experience. I think a person should do what they are comfortable with.

I have both self-adhesive and staple 2x2s in my stockpile; I just grab whichever type happens to be on top of the pile that's the right size. I've had no major incidents with either type, for the past couple of decades at least.
Occasionally I've had self-adhesive ones that don't stick, but I've never seen one where the adhesive fails after a long time; for me, it either fails straight away (within a day of putting the coin in there) or it never fails.
I've heard that some brands of adhesive work much better if you give the exposed glue some "air time" before sealing it up. I'm slow and uncoordinated when I'm making up 2x2s, so my self-adhesives usually get plenty of air time anyways.

I wouldn't touch a pre-tack adhesive anywhere near something I want to archive long term. There are a few (VERY few) used by museums, etc., but we can bet the 2x2s are made in China out of who-knows-what glue.
