Step 1: 2"X2" s

One of the most popular types of coin storage is a 2"X2" cardboard container lined with clear mylar. The coin is placed on the mylar, and the case is folded and stapled shut. With this method, the coin will not slide around in its case while handled.

Pros: Inexpensive, easy to label, compact.
Cons: Coin may be scratched by staples, the plastic in close proximity to the coin can possibly contribute to toning and spotting.

Step 2: Coin flips

Plastic coin flips provide a good mean of storage, allowing you to view the coin without removing it from the holder. Coin flips are not air tight, but they are a good mean for short term storage of coins intended to be untouched. Avoid flips that contain PVC, for over time it decomposes with disastrous results for coins.

Pros: Relatively inexpensive, easy to label.
Cons: Coins can easily slide around inside slides, which could result in small scratches on the coin's surface.

Step 3: Air-tites

Air-tites are manufactured using clear acrylic and a non-yellowing agent. These are compose of two sides, which snap together, creating an air tight seal. This method allows you to see both sides of a coin, without touching the actual coin.

Pros: Compact, low risk of coin damage, highly durable.
Cons: Expensive, difficult to label.

If you staple the envelope, wouldn't that let air in?

Yes, which is why these holders occasionally contribute to toning and spotting. Another downside to this type of storage is that during the manufacturing process, a type of "cardboard dust" is created, which may contribute to unusual toning on your coins, if it is not removed.
I'm going to my (very) local Coin shop for the first time tommor. Are staples okay?
plane phanatic (author)  Flumpkins5 years ago
Yes, but be sure that you do not scratch your coins with the staples.

see is this ok insted of removing the staples i slide my fingernial around the coin to free it from the 2x2

Okay, cool. I'm prob gonna go within the next 3 hours. I'm so excited. It's like the night before a child's christmas. wow I'm a nerd

I started collecting coins...I have a couple wheat pennies and foreign coins, I am also suckish at the states quarter collection. So... if I would put a piece of cloth in a plastic toolbox, put my coins on the cloth carefully, add another cloth layer and close the box, would that be a HORRIBLY HORRIBLE thing to do?! P.S. A foldout album for quarters...is that bad?

You should be fine to start off with the cloth - as long as it is cotton. As you begin to obtain more valuable coins, you should look into the types of storage mentioned in this Instructable. As for the foldout album for quarters - these are fine for circulated coins. If the coins are mint or Uncirculated, you should look in to a holder like this. This type of album is more of a book than a folder, and shows both sides of the coin/s.

do not use the plastic one in step 1!!!!! That causes the coin to get green stuff on it!!!
