My Dansco 7070 is tarnishing some coins I inserted in them last year. The coins are a proof Jefferson nickel, proof modern silver quarter, a sacagewa dollar, and a walking liberty bullion silver dollar. I store the 7070 with the protective sleeve and floral desiccant right next to it in my safe. I broke a couple of slabs on the cheaper proofs to test the book for coin tarnishing, and so far I'm not impressed. Luckily I didn't break slabs on the more expensive coins! As an alternative I'm thinking of creating my own 7070 book using a slab holder. I've seen it done here, and although it's not quite as nostalgic, at least my coins would hold their color once committed to the set. Any thoughts? Edited by FroDaddy

wish mine would, wanna trade? Nah just kidding, I think its the area I live in, nothing tones a coin around here. If you would rather keep the coins in slabs then your option seems like a feasible one to me and you know what they grade and don't have to try to find a place to put the labels and if you ever need to sell the more expensive or highly counterfeited coins you will have one step ahead of most of us that have cracked the coins out because we would probably need to resubmit our coins to get the most money for them

While I'm not part of the Dansco Pep Club around here, the main problem is the environment it's in. The desiccant will keep the humidity low, but it does nothing for all the microscopic impurities floating around.
Experiment: Open an air-tite. Put a MS-63 coin in it. Light a cigarette, blow a puff of smoke on the coin. Now carefully seal the air-tite. Check it every once in awhile for the changes.
That is an exaggerated example, but mimics reality.

I put some proof Lincolns in a Dansco about 10 years ago. They too have a white ring around the edge. Nothing major, but not as sharp as when they went it.

I started my 7070 over 18 months ago. I don't have the slipcover, it just sits on the shelf in my computer room. One of the Buffalo nickels I have in it has gradually turned a golden color, but none of the rest of the coins have changed in any way. I think the Buffalo may have been very lightly toned when I put it in the album. I think the environment has a lot to do with toning. |

I don't smoke, and my home was built 4 years ago. I live in FL so humidity is naturally high though; could that be why?

I'm in Alabama so I've probably got about the same humidity. I've heard minute particles of sulfur or other pollutants in the air contribute to toning. Do you live in an industrial area or near a paper mill?
It sounds like you may need to keep your coins in slabs or air tites. I think one member here puts his albums in large ziplocs & forces as much air out of the bag as possible when he seals 'em.

I don't mean to alarm you, but are you familiar with the Chinese drywall issues being reported in Florida? Some imported drywall is emitting sulphurous gassess. If your coins are toning, it could be a point of concern. Here is a CNN link with some background information: http://www.cnn.com/2009/US/03/24/ch...l/index.htmlI hope this is not an issue for you.

Depending on how they tone, this is not necessarily bad. Can you post any pics of the coins that toned? I am actually hoping mine develop some toning, as it is often attractive in my opinion.
Keeping them in the slabs is never a bad thing, so I would recommend that.

I'm not good at taking pictures, but the most obvious is the silver walker from 1-3 o'clock. This coin was not tarnished at all, and it's ugly to my eyes. The other coins have a smoke-tar yellow hue to them, and it came through a little bit in the pictures. It's much, much more prominent in person. The sacegewa was a nice bright bronze, but now it's dull copper looking. I guess I should mention that I don't like toned coins!     |
