Hello and thank you.
Include a note with the cons as to where the boxes are for future sale.
Well, the simple fact of the matter is mint packaging IS harmful to coins. All that cardboard and paper, it's laced with sulfur and other harmful chemicals like inks and color agents. And those things cause toning, sometimes very ugly toning.
That leaves you with 2 choices, you can leave everything in the original packaging and store it as you please; or you can remove the coins from the original packaging and place them in inert hard plastic coin holders and then store them properly.
And, original packaging includes the hard plastic holders the mint uses for the annual sets - yes, the coins need to be removed from those too. The round hard plastic holders the mint uses for individual coins, (the clear ones), those are fine. But the coins have to be taken out of the boxes they are shipped in, including the velvet boxes.
The idea is to not have anything except inert materials stored anywhere near your coins !
What you want to know is how to organize everything once you remove them from them from all the original packaging. You have a few variable choices, but only a few. There are a few companies who make albums out of inert materials that will hold the Air-Tite type holders, or the slab type holders. And those are about the only choices there are if you wish practical organization for the Air-Tite type holders. If you use the slab type holders, there are slab boxes made of inert materials that the slabs can kept in. And then proper storage methods are required for any/all of those choices.
That's about it, there simply isn't anything else. Assuming of course that you wish to minimize toning/corrosion as much as possible.
Welcome to CT. Great question.
I bought some cardboard boxes that are for storing magazines, and I have stored my coins in them. Can the cardboard boxes be damaging as well?
A lot of questions and few answers. We need to get a chemist on board to teach us the best way to store our collections.
This one is fire resistant and lockable. My wife got it for me used from a store that was closing. It has 7 drawers and was originally for index cards or something like that. It, also, was not expensive as it was being discarded. However, I'm sure it was very expensive new. Check some used office furniture stores or stores that are closing.
Does this include in (inside) it...? Maybe I'm misunderstanding you...help me to understand your thoughts with this...storing coins in close proximity to the OGP, etc. Is there any issue with harming the coins, or...? Thanks.
There are no books on the subject that I'm aware of, but over the years there have been many articles written about in the various coin magazines and coin related websites. And I'd guess there have been hundreds of threads and posts about it here on CT. Just do a search using "proper storage" as your key words and you'll find more than you care to read. And pretty much every one of them will say the same things I said in this thread. And that includes numerous posts made by various chemists who are members of CT.
Nobody likes it, but it's all true.
There is no short and sweet answer because there are simply too many variables. For some you might start seeing things you don't like in a few months, with others it might take years. But toning is inevitable - all coins tone. Toning cannot be stopped, the best you can do is slow it down.
Yes, it is absolutely harmful. As I said above -
All cardboard and paper products are laced with sulfur, it's used when they make the stuff. The only exceptions are archival quality products, and those are few and far between. And no, the US Mint does not use archival quality paper and cardboard - and they never have.
I would also add that many collectors intentionally buy old coin albums, with every single one of them made with cardboard and paper, because they are famous, or infamous depending on your perspective, for causing toning.
How would one remove them from the sealed case?
What do you mean "neutralize"?
