I bought two seperate coin album with silver dimes. Different sellers but in both cases the coins are black around the edges. I have yet to check the backs.
Hard to see in the auction but clear up close. Is this common with coins kept in albums for extended periods of time?

I would say yes I had my Lincoln collection in a warmans and someone had told me that the back of the coins after time will change colors and the fronts will also so I went to a dansco

These were both the cheaper blue folders that have a large picture of the coin on the front. Whitman I believe?

It is the primarily the sulphur in the cardboard that reacts to the metal of the coin in the hole that causes the coin to turn color. The degree of the patina on the coin is dependent on the amount of humidity and temperature changes the folder is subjected to over time. The reverse will usually be darker than the obverse. Dansco uses an archival grade cardboard in their albums which do not react to the coins mounted in the page like the folders which you press the coin into. This 1910 Barber dime in my 20th Century type set was probably taken out of a folder after many years. It was graded MS-64 by PCGS.   Ed ANA LM-3175 |

Agreed. I have everything in Dansco albums, government sealed mint/proof packaging, or sealed Saflips.

Wow that dime still graded as an MS-64?
I'm no expert on grading but how does that work?

Ms64 is a "technical" grade. It only refers to the coins preservation in regards to marks, rubs and other physical flaws caused to the coin. Toning is not considered. Thus a very ugly, blotchy, black coin can grade gem mint or ms65. Interstingly many buyers only consider the technical grade and not the overall appearance. Thus an ugly ms65 often sells for more than a very attractive ms64. Beauty is in the eye of the beholder but it does mean there are some potentially good deals out there.

I never looked at coins that way I always thought a coin would never grade ms unless it looked like it just came from the mint I will defiantly look at coins in a different way .. Thanks for that information

Gyrene7483: Sad to see such a nice silver coin in such a state of toning.
I have never been keen on the concept of the 'push in' type of folder / album. One side of the coins is left exposed and is subject to being damaged when pushed into place. One side of the coin is left open to the air, so you get differential toning. To me this type of storage is only suitable for circulation grade coins taken from circulation, in order to build a date set.
PVC paged binder albums WERE OK, until I learnt the hard way. The plastic PVC pages break down after few years and the coins inside the 2x2's can go dark over about a 10 year period.
I still use mylar 2x2's, but they now go into archival quality album pages.
A few of my most valuable coins live in screw capsules, and are stored in a small safe apart from the main body of the collection.

As is commonly discussed on this Forum about coins in Folders and old Albums. Usually it is the Folders that people have problems with. And it is NOT Sulfur in the paper but usually the glue used to make the Folders. IF your coins are in Folders, note the back of the slots. If they have a shine to them, that is the glue over done area from the process. Some oder Albums too have that problem. In the process glue is spread over the entire sheets of papper that make up the Folders and some Albums. Due to massive production processes, this glue is sort of accepted as OK and is not supposed to effect coins. HOWEVER, as moisture gets to that glue, it is sort of reactivated and stains coins.
And too, Dansco is not the only manufacturer of decent Albums. There is Whitman, Harris, Littleton, Intercept Shield and many, many more. Many think Intercept Shield is of a much higher standard than the others but also cost more.
