Displaying silver collection in a glass cabinet

[PolarPanda]

Hi all, 

I have a question regarding the displaying of my silver (and gold) coin collection. I like to be able to have a look at the nicest parts of my collection, so i'm displaying them in a glass cabinet. All the coins stay in their (original) capsule and / or (collectors) box. Could this be an issue? Is it in some way better to keep the coins in the dark or doesn't this affect the impact from the environment on the coin? I would like to hear your toughts about it and how you guys display your collection! 

Thank you!

Silver's more concerned about moisture I think rather than light so I don't think it'll be a big problem, however maybe someone who displays them in this manner might have more experience!

My issue would be if you were burgled. You could always get them back from the local pawn shop i guess.

I don't buy nice collector's sets to hide them away in a dark safe. I invest my money in nice coins so i could enjoy them. Besides this only a few peoples now about my collection and the room where the cabinet is in is very secure and on the upper floor. Also this is not really a comment that helps me with the question asked

collector box or packs often have glue so beware

Avoid any kind of plastics that contain chlorine, especially PVC, silver chloride is very light sensitive.

Do some flips contain PVC? I've got a load of coins in caps and flips from STG, perhaps I need to ditch the flips?

I don't see how that could affect the coins? They are in between the 'fleece' and protected by a capsule. Or am i saying something completely stupid now and not getting the point? I will give an example. I keep all my lunar years in the boxes from Meinemuenzbox. Does that mean it would be better to take them out? Or what you want to say exactly? Same goes for like the Libertad premium set that comes in a wooden case.

a few years not a problem, 5 years start to have problem , 10 years ur coins start to get marks , 25 years clouded , 35 years fully clouded , 45 years MAYBE damaged green 

because the gule will become gas form and leak through the gaps

So what is according to you the best way then to keep coins for a longer period?

for cabinet , best to be capsules only and then a little camphor at the corner , four corners if u like , no box or those packets

Gold is inert so will not tarnish at all.
Silver will gradually blacken over the years if exposed to sulphur i.e. cigarette smoke or open fire, otherwise should be unaffected.
Finger marks are the worst so avoid handling and if dusting, don't pick up unless wearing clean gloves.

Thank you all for your reactions so far. And what about slabbed coins? Can i just leave them on the shelve from my cabinet or do i have to put them in like an SL50 box from Leuchtturm? It's so hard on finding an option that you can at one side enjoy your coins and on the other side protect them good...

Pre 1980s most coin flips were PVC based. The PVC alone was not the major issue, it was the type of chemical ( hydrogen chloride) added to soften the PVC that was the real killer. With a combination of moisture/humidity as well as potentially large fluctuations in the ambient temperature, along with direct sunlight,  a lot of coins started to mark. Most striking is a green almost oxidization gunk that can affect the coin.

Today however most flips from the likes of Lighthouse, Saflip etc are Maylar based and these are safe to use. Some people maintain that even Maylar should not be seen as a long term storage solution, but there is no indicative proof to this position. Converse to this,  Saflips has been endorsed by NGC for the purpose of grading, and are also used by a number of coin museums/collections for their storage needs

really, i'm surprised? plain old hydrochloric acid? it is either a gas in it's pure form or dissolved in water.

It would be used in the synthesis the PVC but I would imagine any excess would be washed away or dried off.
