Storage of coins

[Coinguy19]

I am a newcomer to this board and I am just beginning to see different articles and things about how many possibly dangerous things are out there to store your coins in that could ruin them. Please respond with what you think are good ways to store coins inexpensively and safely and also what are dangerous ways of storing coins. Thanks

Improper storage can damage your coins in a variety of ways, such as (ugly) tarnish, scratches or PVC damage.

 

If you store coins in clear plastic flips (they come in various sizes, but the most common are 2" x 2"), then be sure to use the mylar (hard plastic - SaFlips is one brand) rather than soft plastic, which can impart PVC damage (green slime).

 

I wouldn't store silver coins in "baggies", as they turn an ugly grey. Using the blue cardboard Whitman folders can also turn silver coins grey/black. Also, if you put new copper coins in them, you'll see a nice thumbprint on the coin in a year or so (you can't get rid of the thumbprint).

 

If the use 2x2s (cardboard with a mylar window) - these frequently have to be stapled shut - sometimes you can scratch the coin when removing the staples at a later date.

 

If you can give us an idea of what coins you want to store, we can give you several ideas of how to store them.

 

One place to look at/buy coin supplies is Brooklyn Gallery. They have discounted prices and fast service.

At this point, I am storing mainly silver, a few gold coins. I have them in the 2x2 cardboard flips. I also have them stored in a cardboard album, which I don't know if it can be dangerous or not. Then I have them in a fireproof safe, however I do have a packet to absorb moisture. Please reply if I am doing something that could damage the coins.

hard crinkly plastic 2x2 non pvc flips

 

then put them in albums and the fire proof safes i do not know much about but they are highly toxic to coins as the materials used inside of the safes are toxic and also hold contain moisture

For hoards of coins, plastic coin tubes work perfectly well. For better coins, or singles, 2x2 flips are perfectly acceptable, cheap and reliable. However, whatever you do, STAY AWAY FROM PVC flips!

Airtite holders would be good for your better coins -- if you can afford them (since the airtites are usually sold in singles as opposed to bunches)...

You've received excellent advice, especially from DaveG, and I would suggest that you regularly change or recharge your moisture-absorber (probably silica) to keep it working. A fireproof safe can impart unattractive toning on coins also. However, if you have gold and circulated silver there is little to worry about as these two items do not tone readily. Lastly, though I like using 2x2 cardboard and mylar flips for the types of coins you list, I would be very careful when using a stapler as the end of the stapler can crimp the rim of your coin if you place the staple too close to it and the staples may rust over time if you store your coins in a moist environment. Good luck.
