like the acetone soak method - following the polarity ladder, you can skip the water part seeing how they were in a moist bag for who knows how long.  |

Wear an N95 or higher respirator around those things. You don't want any of that in your lungs. No coins are worth that. There's a reason why the Katrina and Harvey coins were pretty brutally acid tumble-washed by hazmat companies before being accepted by banks.
To be honest, I would throw them in the trash and not think twice about it.

Concur Marv65. A mask will do nothing to protect against acetone.
N95 masks do not filter gases; they are for particulate matter down to 0.3 micrometers.
An acetone molecule is about 0.0003 micrometers.
They will filter mold spores, which are 1 to 30 micrometers.
But in spite of the topic's title, I doubt mold is an issue here.

The N95 isn't for the acetone. It's for the mold spores.

I have a surplus of N95 masks from the pandemic and they have been fantastic when doing yard-work. My allergies have only gotten worse with age.  That being said, I concur that they work great for blocking the bigger things, but many gaseous aromas still make it to my nostrils.  |

A lot of interesting comments, thanks! The morning after I posted this, I put them in a 5 gallon bucket and used the snap on lid to seal them. After they dried, they all developed a green tint and I was very wary. I think I have a plan though and will report back after I try it with pics.

Just seeing this.
That much acetone might be an explosion/fire hazard.
How about soaking in hydrogen peroxide? It would not take long for it to do its job on the mold.
ps. What a fantastic Mom in Law you have.
pss. How did you dry the coins in a sealed container?
Words of encouragement are one of the major food groups.
We need to consume them regularly to thrive and grow.

I've used acetone in my kitchen for years with no problem - I divorced my wife who couldn't stop her disgusting habit of smoking -  |
