I currently have my florin collection (30 coins approx) in 2x2" self adhesive cardboard/mylar holders. including my 1937 centenary florin (rather valuable) I have those stored in vinyl(?) coin Pages inside a regular binder from an office supplies store. Halfpenny's and pennies None of which are in particularly good condition are stored in a dansco album, or loose in the vinyl coin pages. And I want to get into a more consistent storage system.
Is my current system adequate to preserve the coins, are the self adhesive 2x2 airtight? I haven't noticed any deterioration but am a little concerned about the coins banging together when flipping the pages.
I want to photograph the coins and grade / inspect them. I'm thinking the mylars will cause reflections when photographing, make it more difficult to view them. Is it worthwhile moving them into Quadrum holders so I can still remove the coins for photographing? I guess it would be rather expensive to use Quads, if they need to be stored in boxes/trays etc?

Nothing wrong with 2x2 Mylar coin holders, either stapled ot glued.
The problem can come with clear PVC album pages. Yhe coins inside the 2x2's can darken over a number of years, if the 2x2's they are held in clear PVC pages.
I would advise changing the pages to archival quality pages. It won't cost you too much extra, and is certainly justified, considering the value of the coins, and is an easy swapover.

The cardboard on some of my 2x2s is going slightly off white. However my Importa brand 2x2s are still completely white. Should I replace the off white holders? (I don't know that might be an indication of deterioration )

I have never thought about this before, but bleached white paper will naturally disintegrate over a period of decades. The reason for this has to do with the chlorine based bleaches used to make paper white.
As most people have observed white paper becomes yellow after a long periosd of time.
The paper covering over the cardboard of 2x2's is also chlorine? bleached, but I have never heard of this being a reason why mylar 2x2's should not be used.

Do you think its ok to keep Centenary ($500) florin in 2x2, or hard capsules / quadrums are safer? Although that would mean separating them out into another storage box, I think I'd prefer to keep them together. As a side note I have a few Perth Mint kookaburras, RAM proof sets are still in their presentation cases and cardboard boxes, and a couple of UNC mint sets. Do they require any special consideration to storage? I just have them in a drawer. I was thinking perhaps an acid free archive box or polypropylene snap lock bags |

I may be weird but I just don't like to keep my coins in fancy boxes or slabs. |

Putting higher value coins in hard capsules is a better way to go for the coin, but as you point out, it separates them from the rest of the collection. That is OK if you store just a few higher value coins in a small safe, separate from the main body of the collection.
It is really a matter of choice for yourself, which would be driven at least in part, by any toning or lack of, that you wish to preserve on the high value coins.

Im tending to like the idea of storing the individual high value coin in hard capsules. Does it matter how you store those holders, I don't know if they are air tight?

Quadrums have porous foam rubber, like the airtights with rings. However Quads press together like Whitman holders, so I don't believe they are as airtight. I had hoped the presentation would make up for it, however Quad pages don't click together as positively as the Lighthouse slab pages, so that's a pain.
So I've also looked at Eagle commem albums, and someday I'll probably just buy one to try it out. In the meantime, I'm pretty happy with saflips in printfile heavy duty pages, for most coins, and the ones in ATs are in ziplock bags. Not good presentation, but I keep hoping someone will come along with an alternative to Eagle albums.

If your using 2x2's and those 20 pocket plastic pages placed into a 3 ringed binder, here is a simple solution to your worries. So no coins can bump into another, just place one of the blank plastic 20 pocket pages inbetween each page. And to make it worth the cost, just place a small piece of paper in the slots and on them explain what is on the opposite page.

I've just had the dreaded 2x2s (adhesive) popping open at the top. I've got some mylar saflips, but really do I need to bother heat sealing (to be airtight)? I live in Melbourne, it is not humid. Or perhaps heat sealing stops the coin moving because its tighter.. I also have an archival grade binder with pages.

Or perhaps heat sealing stops the coin moving because its tighter.. I also have an archival grade binder with pages. Simple solution is to just seal all openable sides with 3M clear tape. 1. This will further seal out air 2. Easy to open when you want by slitting it with a knife 3. Cheap since you can get rolls of it for only a little cost 4. When inserting into those 20 pocket plastic pages it will not bind or scratch. |
