    What are the arguments for keeping coins in paper envelopes and in a cardboard box as, say, from Token as opposed to a Lindner or similar display case? Then there are albums which come from, for example, Pre-decimal and no doubt other suppliers.

    It seems to me that keeping the coins in paper envelopes may keep the condition pretty much as when purchased. The Lindner type boxes only show one side and presumably the toning may change?

    The albums allow examination and display of both sides of the coin through 2 layers of plastic - but it is plastic!

    What are the views, pro's and con's? What works for you, and why?

    Roy,
    Keeping your coins in paper envelopes is not a good idea,as the paper contains chemicals that are pretty corrosive,& can react with the metals of the coins themselves.

    You can buy inert plastic coin flips from suppliers such as this one; http://www.brent-krueger.com .

    hmm, but the plastic stuff can damage coins too.

    Scott,
    That is the P.V.C. (polyvinylchloride) plastic flips that are no good for storing coins in.

    I was actually recommending the Mylar-type plastic flips,which are made from an inert plastic.Mylar is also used in making banknote sleeves as well.I can also recommend those as well.

    Aidan et al,

    Looked at brent-krueger - shipping charges to UK on a small order would have been $132.00 +. So plan B.

    There seem to at least 2 options in plastic. One is the all plastic non-PVC flips or the Mylar flips which need to be stapled.

    I was under the impression that acid free paper envelopes were not likely to cause damage?

    Roy,
    Strewth! It sounds like postage from America is a real rip-off!

    I don't know what they would charge for shipping 10,000 plastic flips,& enough long boxes to put them into over here to New Zealand.

    I'll have to get in touch with some contacts in the trade over here to find out how they get theirs in.

    I use a system that has worked well for my coins that are in better condition and are of higher value that are not in slabs. Eagle Coin Holders use inert mylar film pressed between two parts of a polycarbonate frame that is also not harmful to coins. These contain NO PVC and form a nearly airtight seal to protect the coins. I also use Intercept Shield boxes that literally intercept harmful gasses found in our atmosphere from automobiles and other man made emissions. My proof and uncirculated copper and silver coins have not tarnished, changed color (colour) or spotted since using these two coin preservation systems. The Eagle Holders come in either 2x2 white or black frames which can really make the coin stand out against the frame. They also allow you to view the entire coin, even the rim. The downside is they are a bit on the expensive side, but for coins that are of moderate to high value that are not slabbed, this is the next best thing. Here are the links for Eagle and Intercept Shield:
