Banknote Storage

Ok so the minimum safe storage here is notes placed in albums, locked in a steel safe, surrounded by 10 cats, with a couple of Jack Russels thrown into the room as well just to be sure....

Seriously guys, what we need here is a seal-able case. Mice and rats can crawl though opening that small you would not believe. (Some rifle safes I've seen would fail on this point.)

One option I would like to put on the table are products from skbcases.com. (sorry mod if external company suggestions are bad)
These guys make high density polyurethane travel cases for various uses. Cameras, firearms, bows, etc. The firearm cases actually meet Australian standards for transport on airlines.

The main thing is that they are air/water tight and reasonably priced.

Worth a look maybe.

THis is my storage answer. Coins, sets, notes, books.......

The tool box is a great idea for storage... I have looked at a few of those at some auctions and thought if I could get a tool box on the cheap I would use it for coin organization and storage..(Lord Knows I need it)

After reading all the helpful suggestions on here... I wish to revise my suggestion...

Steps:
1) Place notes into hard plastic protectors
2) place those into the ammo crate
3) Place crate(s) into a safe
4) Line the safe with 2 inches of drywall to make it fireproof
5) Lace the drywall with cat nip
6) Place bowls of cat food all around the safe
7) Throw in a few jack russel terriers for good measure
8) Dig a moat around the safe and have frigg'n sharks with lasers on their heads!

After all that... I think you're good to go!
