Storing Coins In Safe Deposit Box

I personally would use and do use, 2x2 mylar flips. I not sure what kind of coins you are trying to store. However, keepingthem in the original packaging almost always add more value, so would keep them In those and get a bigger SD box. Just my 2￠

What a good idea! Give up physical possession of your coins and, possibly, access.

I've had my coins in a SDB for over 7 years. No way I am keeping my more expensive ones in the house even with ADT and lots of guns.
One tip I can tell you, get some moisture absorb packs.
No problems out here in Ca. with humidity but if your in the Midwest, do it.

thanks everyone for the input and links. to give you an idea of a few thinks I was thinking of doing...
Take coins from 1950-64 proof sets out of their boxes/envelopes putting each one in a seperate ziplock, with any info I wasnted to label on it, with a inventory# to match a catalog list and the original box/envelope. This info more for my wife & son should I die, they would be able to reassemble the set if they wanted to sell it.
Also removing coind from anniversry silver eagle sets and do similar. I have 3-5 dets of each, and take up to much room in original packaging to store in SDBox. Also putting in some other high value coins.....
again thanks

Also the A/C usully keeps the humidity at a level good for paper documents which need some humidity to keep from drying out and becoming brittle. Coins do better at a lower humidity level. or coins humidity is an enemy, the water being needed for the reactions that cause toning/tarnish and eventually corrosion. For coins the drier the better any why microenvironments created with ziplocks and silica gel work so well. It makes it easy to create a very low humidity environment.
