Storage

[proof27]

Hi all, Sorry if been asked before, but had a look and couldn't find. What is the absolute best way to store Mint rolls? I have them in coin bags from bank at the moment and I need better sealing. Thanks

Fulvio might have a clue on this topic.

LDPE is neither oxygen nor moisture proof. As I found out the hard way when I destroyed a heap of Coronation $2. Plus, coin bags have holes and mint bags have slits.

What I currently do is I roll up the bags to exclude as much air as possible and add extra layers. Then I pack them into additional bags (for $2, a bag will hold four rolls. And finally I put them in a PP bucket like the ones Coles sell their lollies in at various times of the year. Oh, and I throw in a couple of bags of oxygen and moisture adsorbers as well.

I've documented this here with piccies, back around the time of the Woolies Olympic coins. And I tracked down a manufacturer and proposed a bulk buy, but nobody seemed interested. Similarly, nobody was interested when I found a supplier of PP bags sized to fit the mint set cards for the Olympics and later series. Oh well.

Don't worry McDuck, your efforts, products and methods were well and truly noted (even the chip packet scenario). :good:

Speaking of chip packets....

I had a go at using one with an Aldi vacuum sealer. Not at all successful. It refused to suck the air out of it. Probably because of the smooth inner surface being pressed tight by the foam seal around the vacuum chamber.

Must give this a bit of thought, methinks.
