Do not apply heat! Applying heat - even low heat as you mention, is a great way to accelerate chemical reactions and begin toning funny colors. Especially if you're just letting them sit and "air" out. You are not removing the smoke chemicals, you're just airing them out. Applying heat will start to turn colors quickly. And that includes sunshine!
Heat is one of the worse things you can do to them. Airing them takes time, lots of time so be patient.
There's at least one thread on CT of putting copper coins in a toaster oven to get them to tone pretty colors. you could always use jelly to protect the surfaces back in 2018/19 we had threads of AT v NT of all those "gassed" slabs to get pretty colors and streaks on silver coins, and how to change the color of copper coins using heat. And some coins that had untoned lines like on a toaster rack. I think 200 to 350 degrees was the magic mark for copper in a toaster oven. But those temps under hot coils might ignite the nicotine oils so you'll want to preheat .... You can use a regular toaster too .... but .... you might just want to use a fan to dry them off quicker.
Yeah, and it get real interesting … shocking even … when a coin slips through the heating grid and contacts the grounded case of the toaster. Cal
I have never thought much about removing smoke smells from coins. The only time I remember someone sniffing a coin was when an exonumia dealer told me to smell a Monitor Civil War token to see if it was a rare variety in brass. He claimed the brass ones smelled like fish. As for other smells, if you went to coin shows in the 1970s, the cigar smoke was as think as a fog. It really was awful. That's one good think that has come from indoor smoking bans.
Nah, a regular electric oven with the cents on a strip of aluminum foil just under the element. Set temp to 450 degrees and turn it off when it reaches temperature.
Update: the coins have been moved a few times into different areas and aired out but still smell strongly of smoke. I’ve decided to soak them in distilled water over night and then lay out to dry.
That's a bunch of bull. You are just pissed at the guy that had the coins so long. All bags of cents have a smell and it goes away if you just air them out.
It appears the only one angry here is you. The coins still smell and I’m now soaking them in distilled water. If that upsets you, kindly find a new thread to read.
Also, if you don’t believe me, I’ll mail you some of the coins for you to smell for yourself. Then you can apologize publicly for being so rude. Do you accept?
Not sure where this heat's coming from. I know I can't smell the coins from here, but don't see why I should disbelieve OP...?
If the OP is smoking while smelling the coins, then do each activity separately. This is the reason the movies with the sex scenes show the smoking after the sex scene. Do each activity separately. Now, of course, the Op will come back and state he was not smoking while smelling, and/or does not smoke, or some such denial, and we will all know it is not true. They always say that after the fact. I know stuff.
