Has anyone had any long-term experience with the self-adhesive style 2x2 cardboard holders? I have concerns about the adhesive affecting the coin in some way. The reason I ask is I was given an assortment of different size holders of this type but am afraid to put anything in them except tokens of little or no value that I then was able to organize in a binder. They are very handy, no stapling and all, but I am wary.
Just wanted to add that I too am looking for information on the long (or short) term effects of this type of holder. Anyone?
I've heard bad things about fumes from the adhesive glue, but I don't think they've been around long enough for anybody to have very long term experience with them. I've had bad things happen when removing the staples on the regular kind.
I don't trust the adhesive self-sealing 2x2's until I hear and see more positive feedback. I use 2x2 standard cardboards with 4 staples (crimped with my flat head pliers), Avery labels (80 per sheet) printed out with the year, mint mark, and mintage numbers all displayed nicely in a 3 ring binder. For the good stuff, they go into 2x2 Intercept Shield holders. Protection and display are both a must!
Self adhesive 2x2s +*+* I collect Australian Coins and there has been much discussion on the Australian forum about self adhesive 2x2s. Like everything else it has to do with Quality. The cheap ones have caused some toning. The more expensive ones seem to do very well and you do not have air or staple rust affecting your coins. I am posting some information that I have cut from the Australian forum and my thanks to Niksfree for the post Hi my understanding of the self adhesive coin holders is that the glues become inert when bonded together, toning would be from holders made before the introduction of mylar and when stored were not in a cool environment. Using the stapled ones exposes the coin to stains from corrosion of the staples which are not made to a standard but a price and will deteriate when moisture is present in the air. NOTE When using the self adhesive coin holder its important also to allow the adhesive to activate when the protective label is peeled off by allowing it to stand for a few minutes before squeezing together the two halves. by using a holder that is as close in size to the coin also helps as no air which may have moisture in it, to be trapped with the coin, this is a problem in humid regions and will cause toning. to help eliminate this problem further try and seal your coins in an air conditioned environment after allowing them to sit for an hour to stabilise in the room along with the holders. Hope this will help those experiencing problems with the coin holders.
One word....AIRTITES!! No glue, no staples, no worry, just good clean long-term protection. And the coins look much better when displayed in airtites.
