Eco-Friendly Coin Storage

[Fulvio]

Wages is what I withdraw to pay for coins :angel:

Wages aren't for coins. Wages are for keeping you alive and healthy enough to be able to buy coins.

Corpses who failed to keep a roof over the missus and food in her belly don't tend to get in a lot of noodling.

Savings are like leftovers.. what's left on the table after you're sated.

why go to all that trouble and then roll them in various sizes (i.e. - I see rolls with 34, then 35)
shouldn't you have it same as a bag

25 coin s per roll? aren't they $50bags?

Because the aim is to pack them tight, and the bags vary slightly, that's why. 33, 34, 35 seems to be the range.

$50 bags are needed for commerce, yes. That's why the recycled Armaguard bags with the spacers to make $50 fit tightly.

And why tight? Because if they're loose, they will rub every time the bag moves, and then they will stop being UNC. Not to mention contaminated urban air is a bad thing in your storage.

[robbiegal]

yeah
but without the label
no one is goanna know how many coins are in the rolls
if you are consistent then every roll picked up is $50 face value or 25 by number
and they will pack better in even lengths

it's my orderly brain kicking in here

[Fulvio]

but without the label

But its on the label. Which is an integral part of this system.

I do do $50 bags, which are the rejects I throw back in the pond. Trust me, they're not neat, and there is no easy way to make them so, because you can't weld close in to the roll, and you can't reliably pre-cut the exact size.

I tried many, many different versions before settling on this in the end.

But hey, I'm not here to dictate to anyone how to do it. I just document what I did, in as much detail as possible, and explain the reasoning that led to a given point. If you do it different, fantastic. Just let us know if you find solutions that work better, if you would. I'd love to learn.

The end goal is to recycle waste products and provide stable, secure long-term bulk storage. Anything that does that is good I reckon.

[robbiegal]

yeah
all good

i'm a sewer - and if the row isn't straight and even
it gets unpicked - resewn and unpicked & resewn - until it's straight
so for my eyes - one coin higher out of a few rolls - would erk me

so if I was making the rolls
they'd all be the same height so that I could put them in neat little rows and marvel at what a brilliant organiser I am !! ha ha

well done - it looks great
albeit not as level as this gal would like ém!!!
ps

my son works in a book shop
and he wraps the books in what looks like cling wrap roll of clear sheets
wraps the book
then goes over it with a hairdryer

the cling wrap stuff shrinks really quickly
and presto
the book is wrapped really tight

wonder if it would work on rolls?

maybe he could get me some of the stuff and i'll do an experiment for you

[Fulvio]

Certainly doable. Just reject the bags that don't conform. You could also apply a bit more brute force and make them all 35, maybe. LDPE has a certain amount of give, though it does tend to buckle, and the seam may split sometime down the track. Give it a try.

wonder if it would work on rolls?

Shrinkwrap certainly would work. Its just a matter of having the right dispenser so you don't get a big mess.

However (you just knew there was a catch, didn't you?) there are many different shrinkwrap films, and they differ in both mechanical properties and chemical composition. And some of them contain that dreaded PVC poison. While I've used a number of films industrially, I've never needed to investigate their archival qualities, so I can't offer any guidance at all.

By all means do some research and report back. But keep in mind they're not cheap, and you wouldn't be recycling waste plastic. Quite the opposite in fact.

[robbiegal]

oh
good points

[robbiegal]

here are my rolls
now, ... they don't look as nice as yours

2 X 20 - perth and Melbourne
they are in that pp stuff
and I have been trying to figure out how to make a tight neat roll as they are a little loose
cheers rob


in case you are wondering - that is fluff from my wooly jumper

[Fulvio]

Polypropylene is stiffer than Polyethylene. That's why they make album pages out of it. And why it crumples rather than bends.

I can't tell from those pics where you welded them, or how you aligned the coins in the bags. These aren't those little self-adhesive bags, are they? If they are, they're not airtight.

[robbiegal]

yeah
just the bag seal
no they are not airtight

should they be?
I thought coins need to breathe

[Fulvio]

I thought coins need to breathe

Air has lots of nasty stuff in it, especially in urban environments. Some of the chemicals will react with your coins, producing toning, verdigris or corrosion. I prefer to exclude as much air as possible.

Meanwhile, back at the packing line...

As I'm finally happy with the rolls, I figured it was time to go back to the individual coins, since I wasn't happy with the Excel solution. After about a dozen generations built on a modified roll databse, this is the current 2x2 label:



And a print preview:



Not quite happy with the heat sealing yet... I'm putting a stripe across the middle of the coin to stop it rotating in the sleeve, but for some reason its burning holes through the plastic adjacent to the coin.

No idea why.. every other seal is perfect, but this one consistently does this. Not that I think it lets air in, it seems to be sealed all around the holes, but it looks ugly... *sigh* More development to be done, eh?

Oh, and my bother-in-law dropped by as I was showing dad the latest generation, and decided he had to have it! I felt guilty about taking $10 off him, so I gave him a standard 2013 as a bonus with instructions to wait until we know mintages before spending it.

hey RG why not roll them in paper first like the good ole days..just a thought mate
