I found something that looked like rust on some ben Franklin halves I purchased from a pawn shop in a Whitman album. I soaked them in acetone followed by a hot tap water soak and that got rid of it. Pictures are really needed here. |

I had placed a silver dime, silver quarter, nickle, copper cent and a counterfeit Trade dollar on top of my hot water heater in a envelope to see how they would tone. I had forgot about the coins for a couple of years until my hot water heater was leaking. The top of the hot water heater was covered in heavy rust water and the envelope had rotted away. All the coins had a coating of the rust on them. I used acetone on all the coins, but some of the coins had a stain after the rust sediment was removed. The coin that the rust would not come off was the counterfeit Trade dollar. Edited by Slider23

I had my suspicions that the coins had taken water while stored away in a metal box. I paid accordingly for the rust/oxidation stains, got them less than melt. They are not very desirable coins as far as eye appeal, but they're good enough for me. I'll get some pics up later. I will also try some acetone, never have gone that route before, but I've read about it on this forum for years. Thanks again!

 with coinfrog , silver does not rust. It's an environmental issue . Some stains can be removed from silver coins ,but keep in mind some can't . good luck with them .  |

That silver does not rust is true, but to get the idea of the effects of direct contact ground burial may have on an ancient silver coin, look at some of the lower valued examples of ancient silver coins, where wear has not been a major factor in it's degradation.

Rust is an ambiguous term. Basically used to describe Oxidation with Iron. However, rusting on any metal is basically combining with Oxygen and almost all metals will do that in some form or other. Such as Nitrates or Sulfates. With Silver, if in the area of any Chlorine or Fluorine and moisture, dark spots will be from those chemicals. And as anyone knows Silver does what is called Tarnishing.
another term for rusting.
If those spots are from any chemical reaction with the coins, removing such spots should also leave marks.

Acetone won't hurt anything, but I don't know how much it will help.

I'm going to say that brown stain might be leached out of the paper. Flood water soup is nasty, toxic liquid. Get those coins out of the folder. Acetone dip cannot hurt. Peace Roy

Better late than never. The issue is that some iron debris was on the die when it was struck. The "iron" metal rusts....

Blast from the past, posting pictures on flicker? I don't even remember flicker, but I do remember purchasing those halves.
