After inspecting my inherited Mercury dime Collection I noticed all the coins obverses were great with good luster but when I took them out of the paper holders all the reverses were Matte, Chalky and dull - Does anyone know why this would have happened. I enclosed a picture of the holder I took them out of - and an example of the dimes..    |

I'm pretty sure it's caused by the glue on the paper backing. My Whitman folders do the same thing...which is why I started new sets in albums with plastic slides.

Thank you! Can they be cleaned or repaired?

Not sure if there are any known "fixes". Others will chime in soon.

To be honest, to me they don't look terrible. At least they have original uncleaned surfaces. Most I would do is soak them in 100% acetone, which can be found in hardware stores. It is not called cleaning, but conserving, as it doesn't alter the metal. It probably won't remove the toning, but at least it'll get the organic debris off. to the CCF! Edited by SilverDollar2017

to the Community! For the record, this is a Dansco folder, not an album. An album allows you to see both sides of the coins and would not have affected the reverse as this folder has. |

Yes with the 100% acetone. Leave them soak overnight, rinse with distilled water, and cross your fingers. If that doesn't help then like stated, just put them in an album as is.

and good advise. An acetone soak would be good for them. |

Good advice so far--the only thing I would add is to handle them by the edges. Welcome to CCF @HK!

Because of the evenness of the tarnishy surface toning, I think it's probably due to alum in the old red paper, either due to the effect of the acidity or the sulfur content. Alum was commonly used to set rosin sizing.
