I've been collecting coins for a long time and just started putting them in Dansco Folders. Some of the coins have black specs on them and some have green. I think the black is deeper into the coin as I tried using the vinegar and salt on a few junk coins and it wouldn't come off. My biggest concern is that I want to upgrade some of my coins in the folder to a higher grade and they cost over $ 100 each. Is there a chance that the new coin in the window next to the black/green coin might take on some of the same caratoristics of that coin. Thanks

That is my biggest concern with my cents so I decided to go with 2x2s and then organize them in a 3 ring binder with 2x2 holding pages. I dont want anything getting on my coins.although others my have different ways that would protect them just as good.

to CCF.

It sounds like you are asking if there might be cross contamination from your exisiting coins over to upgraded ones you might buy.

I'm not sure what the black might be however the greenish might be verdigris.

"Verdigris is the common name for a green pigment obtained through the application of acetic acid to copper plates[1] or the natural patina formed when copper, brass or bronze is weathered and exposed to air or seawater over a period of time. It is usually a basic copper carbonate, but near the sea will be a basic copper chloride.[2] If acetic acid is present at the time of weathering, it may consist of copper(II) acetate."

Without your coins being housed in air tights I suspect that is possible expecially if you store them together.

There are many more knowledgable CCF members here, even some chemists, who might chime in with there knowledge.

Best of Luck,

Jim

The black spots might be carbon spots which are frequently found on copper coins. I am not completely sure but I don't think you can remove them without causing damage to the coin.

To start with you said Folder, not Album. For me that is sort of like a bad word. Folders are not the best thing for long term storage of coins. Not even for most coins at all
1. You normally push coins into those slots with fingers or thumbs. That leaves prints on the coins.
2. You can not see the backs of those coins so sort of ruins the effect.
3. Most Folders are made with a process of gluing the back sheets to the slotted cardboard sheet. This glue is noticable in the rear of the slots. That glue, when exposed to moisture gets on the coins.
4. In the process of removing most coins, you push them filolently out of the slot and in many instances push right through the back.
5. Every time you open a Folder you expose those coins to your breath, spit, caughing, sneezing, moisture in the air, more fingerprints, your cat's hairs, etc.
6. On the brighter side they are excessively cheaper than an Album.
I suggest you switch to an Album although much more expensive. However, still better than replacing all your coins.

First, I'd stop the vinegar and salt treatment immediately. Vinegar is an acid and the salt is corrosive, and depending on what you're using to wipe them off, you could be really damaging your coins, more than you might be aware of. Take a bit of time to read the various forums here and you'll find some excellent advice regarding removing crud from your coins without hurting them.

You don't explain which coins exactly which coins you are having issues with... post '82 zinc pennies sometimes develop unknown black spots, and sometimes older copper coins have circulation build-up crud or or issues from how they are stored. Can you show us a few photos of the problems you have? Images might help us identify the problems you are having.

Also. thinking longer term, you might want to consider purchasing a coin album rather than a folder, especially if you are planning on obtaining some of those "$100" coins you mentioned. It's all about protection for them there coins.

And,

You've come to the right place for help!

Welcome to the forum...

I would never, ever use an album OR a folder to store coins. BOTH are chemical minefields and will...WILL damage your coins, ESPECIALLY red copper. Dansco albums are one of the worst for turning coins long-term, but ALL of the commercially available folders and albums will damage coins.

Use archival safe flips and 20-pocket pages. I've used them for a little over 20 years and have never had a problem.

With regard to the vinegar and salt - that's probably THE worst thing you could be doing to the coins. Cleaning coins ruins coins. End of story, no exceptions. Properly conserving a coin and removing contaminants is something best left to those who know what the contaminants are, what best removes them, and which coins are proper candidates on a one to one basis. Not all coins can be helped, and knowing the difference is half the battle.

If you want to learn how to do it, you will need patience, a lot of pocket change, and a heck of a lot of experience. "Reading up" on it will NOT give you a good start, because there's frankly more bad advice out there on how to 'clean' coins than there is good advice.

A couple of definite no-nos...acetone, acids, and brasso or anything with bleach, ammonia, or other corrosives.

Your 1951 cent is corroded from having been buried in the ground. It is not discolored that way by a folder or album. It's NOT a candidate for any sort of conservation, and it would not be worth the effort anyway. It's a five-cent coin.

Bold statement, coppercoins. I think there are a lot of people here on this forum and elsewhere who would probably disagree with you from years of experience, but you are entitled to your opinion. Personally, I use an Intercept Shield album for my Lincoln cents which is specifically made of acid-free archival materials.

valentine, there is a search box located in the top left corner of every CCF page... that is the best way to find information on coin care.

Yes he is. I agree on the folders, but I am one that disagrees on the albums.

I have used Dansco albums for almost 27 years with no problems. In my opinion, how you store the albums (or coins in general) is very important; stable temperature and low humidity.

DanMichSr, I think you should do what ever YOU want to do. Its YOUR hobby, You should preserve them however you want. If you want to clean them, learn the proper way, and if you want to put them in a dansco, do it. I tried the two by two coin sheet method and just didnt like it. I think my collection looks much better displayed in a dansco. Display them however you want!
