Understand mainly humidity/moisture, temperature and how you store a coin is important. My question has to do with maybe the invisible. Just as an example - you get a roll of coins from your bank. Circulated coins - and you find 10 coins you want to add to 2x2's or to your folder or album. Do you do anything before adding them to your collection. Rinse in soap/dish detergent and water? Rinse with acetone? OR - do you just add them. Not really talking about dirty looking coins - but may 10 year old EF or higher grade. Appreciate any help or advise you can provide me.

Although some may differ in thought, I rinse any newly obtained coins with acetone. Once you watch a beautiful coin develop a fingerprint or saliva spots, that might have been eliminated with an acetone rinse if done BEFORE the condition shows, otherwise if you can see them, it is too late IMO.

 I always use the acetone. It wont hurt, and far better to be safe than sorry. Just remember it has to be pure acetone from a hardware store, not nail polish remover, which isn't pure. |

Thanks for your reply. I am going to adopt the same method. I really have not been doing anything and recently found that is a mistake. Read a post about - "Do You Enjoy Your Coin Collection" - decided to pull out some that I put into 2X2's long ago. Real sure they did not look like they do now when I put them in my collection. Again - Thanks for your replies and helping me out. Appreciated...

I know that cardboard 2x2 are inexpensive, and the mylar inner liner supposedly separates the coin from the cardboard, but if you staple the cardboard or if cardboard "dust" gets near the coin, odd toning or corrosion can occur over a long period of time. Consider storing better coins in non-plasticized safety flips, or even better archival mylar or non-vinyl plastic flips.

Question: What is the proper way to staple a 2x2? I have seen that some people staple them close to the mylar, while others staple them on the edges of the 2x2. Both hold the coin equally well, in my experience, so long as it is the correct 2x2 to begin with...

What is the technique for soaking a coin in acetone? How long to soak it? Can you reuse the acetone for several coins? Du you use a tweezers to remove the coin? Do you dry it with anything or let it dry on its own?

No such thing as proper way. Just a lot of common CENTS. For one thing not much purpose stapling the hindged side. So that leaves 3 sides left. If you staple to close to the coin, you may hit the plastic leaving a hole for air to enter. If to far from the coin, it may move around if you used a flip of a larger size than the coin. A cent in a nickel flip for example. Always flatten the staples with a pair of pliers so they don't scratch another coin in a flip. Quote:

Do you dry it with anything or let it dry on its own? As already noted there are many posts here about that stuff. If you don't like the one suggested already, just try a search on this forum for Acetone. As a short cut I'll just say place the coin in a plastic bottle, add the Acetone, place outside in the Sun for one year.  Just kidding you know or I hope you know. Don't do this. Mainly do not reuse Acetone, do not use metal items to remove the coins, do not put in anything but glass, Use in well ventillated areas only, no flames or sparks in the area. |

The staples are not archival and in time may oxidize (rust) slightly on the surface, and since they penetrate the mylar inner lining of cardboard 2x2, the atmosphere around the coin can also be in contact with the staple, causing toning or eventually corrosion. I live in a very dry environment and the staples were not visibly rusty. The below Morgan lived in a stapled cardboard 2x2 for 25 years in my possession and the arrows show where the staples were. No problem, but a little strange looking. In a moist environment, it would probably occur sooner. Jim  |

Jim, I've ran into the same problem. I bought a Indian/Buffalo Comm Proof at a local auction that was removed from it's original holder and put in a 2x2 that was too small and the staples were right up against the coin causing rust damage. I only paid spot for it though  ...but it was a shame to see such a nice coin ruined by mishandling. |
