Hello, again I would like to ask you a question regarding coin storage and the chemical environment. I have my coins sealed in acrylic capsules. I currently store them in a polypropylene box, but would like to put them in a metal box (looks better). I don't know what a tom can be made of - ?aluminum? ?alloy? ?steel? I want to ask, is this safe for my coins? Is it possible for any chemical to leak out over time? Is it bad that the box has some designs painted on the outside (also a chemical)?
By coins I mean materials such as silver, aluminium, copper, etc.
Is it chemically ok? Won't it be tarnishing over time? *coins
Ahojky.
No one can give you 100% security in a metal box, the inside of the boxes is covered with a metal film, and when you close the box, they should not breathe on each other with the air from the surroundings, the amount of coins they are stored. There is a simpler method - just buy a vacuum-sealing machine with safe food bags. Choose a nice thin - transparent. Your coins are mostly silver, buy plastic capsules according to the size of the coins. Place them in a bag next to each other, the device sucks out the air in a sealed bag and you have a nice view of the coins and the assurance of 1000 years of safe storage against moisture, mold and chemicals. and at the same time you can see the coins. Choose the size for the quantity yourself. Food storage bags are strictly monitored - their quality is free of harmful substances.
It depends on the type of metal. If different metal alloys are in contact with each other, there will be an reaction, which, in practice, do not give good results. An example; if stainlesssteel parts are connected with ordinairy bolts and nuts, very soon those bolts and nuts are completely gone, much faster than without the contact of the stainless steel. This are offcourse chemical-reactions, my knowledge on this field is very limited, definitly someone
else here can explain you the science behind it. In short my advice do not mix differnt metals if you store it for long and the envoirement is maybe
a little bit moisture. Sorry for my farmers english.
Pyrex storage Containers would be good. Air tight lids. Very tough glass! but that is very heavy.
I did a better job. I bought this glass jar. Glass is an inert material, so everything will be fine. However, there were some papers inside (see picture). Even if I remove them, could it hurt the coins in the long run? It would make sense to me that it wouldn't, because if I reach inside to get the coins in the capsules, I'll touch the surface anyway. Just asking to be sure!! Thanks.

The jar is Italian, so nothing bad can happen to your coins. I would stay away from Russian jars though
What are you all talking about they are probably not state treasures or crumbling to dust at the slightest presents of air. If I read it correctly they are already in capsules or other protective casings so put them in a damn box nothing much will happen unless you leave them in a climate that has a high fluctuation of temperature and/or has high humidity.
You might want to look into pumping some inert gas into your glass jar, such as Nitrogen or Argon, to be sure.
In that case he has to use the rubber seal again. Or maybe better to find a similar gasket
made out of silicone. And store the jar out of (sun)light. In no circumstances ever open the jar again.
Yes, my coins are in capsules. The gasket wasn't natively assembled to the jar, so I removed it, because I am afraid of the unknown plastic material.
So, just putting it into the jar without the gasket will be fine? I am still wondering about the air - I eat, sleep and fart in the room. Maybe, what about heating in winter? It is also a sudden temperature change. Many people have their coins in coin trays (similar environment and situation - no gasket etc. against the air) and its ok.
