Best way to store coin rolls?

Happy new year everyone. There is a lot discussion on forum already on how to store your precious coins. But what about coin rolls?

What is the best way to store them? Keen to hear how people are keeping them safe in good condition for the long term.

If it were me I would not store coins especially decimals in paper rolls.
It will affect the coins long term.
My guess is that modern alloys will look ugly eventually.

There's got to be a good way short of cracking them open?

Heat sealed plastic bags is one way to store rolled coins.

Thanks Goldseeker :good:

Is polythylene safe for coins?

It would go nicely with something like this

OK looks like I need polypropylene. This stuff is tricky. :dodgy:

I have been using the small plastic bags that one can get from the bank that holds the coins.

Oh OK. That's a good idea.

The expert who would give half a page of storage comments is currently very ill in hospital. If he was able he would certainly put you onto the correct path for storage.

I just can't find his previous comments that he has made on the forum re this subject.

Very sorry to hear that. Hope he gets better soon.

Hehe... read the story of what happened next, Goldy. I'm home though.

LDPE (what the bank bags are made of) is fine, BUT it turns out not to be 100% impervious to gasses. As I found out when my coronation bags turned green after lying on a foam pillow for months.

What I would do is, individually seal the rolls in LDPE, then put the rolls in a thick Armaguard LDPE sack, then seal THAT in a chip bag. Preferrably after you hose the crumbs out of it of course.

Chip bags are multilayer BoPET (Mylar), with printing on the inside and an aluminium layer in the middle. So they're kinda like helium baloons, and you know how long it takes Helium to escape from THOSE.

PET would work, but is rigid of course, as in soft drink bottles. Polypropylene or Acrylic would be great, and there are tubes made out of those, but they're not cheap. So the freebie multilayer approach is the way I'd do it. The way I DO do it in fact.

I knew you would respond Fulvio, thanks.

Trust you are getting better.

back on track now.............

Very impressive research Fulvio.

And glad to hear you are feeling better.

My heat sealer has arrived from eBay. I have been busy sealing my rolls in coin bags from the bank. Also purchased some Polypropylene bags and sealed the bank coin bags with coins inside as well. The mylar bags have yet to arrived. Might be over doing it - 3 layers!

Have been playing with the heat sealer. Sealed the $1 Terra Australis folders in the Polypropylene bags. Looking very professional.

Very. What did the PP bags cost you?

kchan1111 · January 08, 2015, 09:19:13 AM

$11 for 100 + $4 shipping, a generous 155x230mm or A5 size. If you are careful you can individually sealed 3 of the RAM size coin folders into a single one. Here's the link.

The title says cellophane (which is a wood) rather than polypropylene (crude oil). Yeah I looked it up! But the seller assured me it's polypropylene because everyone searches for cellophane. Other sizes available from same seller.

I don't eat chips so I didn't want to spend $2 just for leftover bag. Here are the Aluminium mylar bags:
