Any guesses as to what caused the problem on the reverse? The front is not nearly as bad.   |

It appears to have been glued to something for quite some time and left in a poor environment.

 it was glued on to something. For example, a belt buckle or a money clip. |

I agree, it appears to be glue and hopefully an acetone bath helps. If you do, please share the after bath pics

if the acetone doesn't help I would glue that son of a mint onto my money clip, it would look pretty cool or just keep it as scrap silver

Be very surprised if it doesn't. I'm not so sure about the toning, though - don't know if that's on the coin or the glue. It might be a problem later, which may be addressable. This one will require patience. Don't be afraid to devote a few overnight soaks. |

What Dave said. Soak this girl for a good 24 hours, dump and re soak. It will take afew times to clean her up.

The REST of the story is that I found this and 4 other 1923s while helping ready my mom-in-law's house for sale. All five of them had this problem on the reverse, although THIS ONE was the worst of the lot. My initial guess was that the coin had lain in water or some other liquid while on a very flat, hard surface (like a glass tabletop) and had lain there until the liquid had completely dried. Sort of like they were on display and got wet without the display-er being aware of the problem until after they had dried. Upon looking closely through a loupe I cannot detect any substance clinging to the surface - it's just appears to be discolored/toned/tarnished.
I'll definitely give them an acetone bath and post the AFTER photos.
If this is a byproduct of laying in water will acetone still affect the appearance?
(EDIT) PS: When I found them, they were in an old purse along with some Morgans, silver halves and clad halves - sort of like loose pocket change!!

Update: It's been soaking in acetone for a little over 33 hours now. If it's changed any at all, it's sure not much.
I'll leave it in there a couple more days.

I am not sure if this question would need its own thread but I have been curious about the acetone. I have always heard "Never clean a coin" but it seems many here recommend acetone for some coins. What does it do specifically and what (if any) difference is there between using acetone and "cleaning" a coin? Thanks all!

Acetone is an organic solvent that is neutral for coinage metals, it will only remove organic surface contaminants such as glue and oils and does not remove toning or harm patina. It's use is not considered to be "cleaning" in the bad numismatic sense since coinage metal is not affected, it would fall into the "conservation" category since its use prevents further harm to a coin from the presence of contaminants.

Ok thank you @biokemist! So last question on that topic, where would one get some acetone for conservation purposes? Do they carry at the local Walmart? Thanks again |
