Best way keeping rolls.. ?

Hello! :hail:

What is the best way to keep rolls? In Quebec, here we usually use plastic rolls, but are they PVC free, I don't know. Anyone knows? Else, I know there are paper rolls... Maybe they do less damages to the coins?

Thanks!

Hi Max
I use numis square coin tubes they are archival safe go to jp's corner web site for the price list very nice people there.

 

old timers used aluminum foil

 

Aluminium foil??? hya:
That's not a bad idea... if it does nothing wrong to the coins... :thumb:
Thanks about that!

Thanks GDJMSP for your answer, I won't use them to store coins I want to keep! :bow:

And Bruce, I'll take a look at these! But if Al foil does the same job and costs less, I'll probably go with it. Thank you too!

:kewl: Max

 

but it does, so i wouldn't use it
unless anybody else knows more and i'm wrong?

 

I have some old silver coins that have been in foil for decades and man are they shiney.

 

Uh oh..

Thanks for the advices!!! I'll try to take care for the moisture... Dunno how, but I'll try!

Yup!! thought about that!! I suppose that .. if I put some little silica bags where I store my coins.. even if they are in alu foil it should help a lot... Lets get some.. but now where can I get this (I work in a hardware.. there are that kind of bags with most iron tools like bench saws.. interesting...)

Max

 

Ohh okay, thanks!!

But... how do I reactivate it???? I don't really know how it works.....

Thanks
Max

 

Okay!! great!

but.. about the mint sets... if they are sealed just after being made.. and.. emm they stay in that plastic bag for 41 years, how in the world could they react with something?.. I guess that's not completely hermetic...

 

Gel packs are nice but limited to useage in small confined areas only. If your coins are in a house just get one of those things called a dehumidifier. I keep most of my coins in my basement and live in a highly humid area. One large dehumidifier works just great. As an experiment I hung large gel packs all over the basement for about a month. My Hygrometer registered a never ending 45 % and at times during outside rain it jumped up to 60 % for a few days. Put the dehumidifier back on and the hygrometer registered 25 % in a few days. As to plastic tubes if they are dangerous to coins it's news to me. I've had some in them since about the 1960 ara. I've been putting all denominations in them for many, many years. Regarless of the material they are composed of they will not effect the coins unless exposed to high temperatures. Most, not all, plastics are stable compounds and do not effect matallic items such as coins unless exposed to sufficient temperatures to insite a reaction or melting.
The usage of any paper product for long term storage of coins is not a great idea. Paper is pourous and the slightest gases that could react with the metal of a coin could and will penitrate the paper. So unless the paper rolled coins are kept in a stable, moisture free atmosphere, they will eventually be effected.
As to aluminum foil, if any one does use this for storage they must make sure of little to no temperature changes. It does work but if there are constant temperature changes, the coins will be effected by a thing called electrolysis. Any time any two dissimilar metals touch each other they create a flow of electrons which is for a short period of time trivial. But for long terms and with temperature changes the coins will be distroyed. This is the principal of a thermocouple as used in piping, duct work and large machines all over the world. An example is the duct work at a power station where a thermowell is inserted into the duct. This is then followed by two dissimilar wires connected at that point. For every degree of temperature change an electron flow goes through the wires to a gauge at the control board indicating that change.
Back to the plastic rolls. I've got approximately 500 plastic rolls of coins and no problems of any kind.
