"Silvio, zinc ions may react with impurities in acetone, but metallic zinc will not react with pure acetone without assistance".
The Zn ions no but do not exist zinc without the protector envelope of the ZnO. this react with the acetone, become catalyst and has thermal reactions. this reaction will develop some gases (acetone gases) which go to depolarize some Zn ions. It is a funny reaction because many medical questions was answered by this reaction. Forgot to put the acetone formula : C3H6O
So calculate yourself the ZnO+C3H6O = ? you has the response. Becoming catalytic mean will be a chain of reactions. Some conditions must be present sure.
I like your approach of the science with our hobby.

No worries on learning to submit anything for grading, or learning to sell some coins if you desire at some point. Some people here forget that not everyone is an expert. They are just discussing that some people have created artificially toned coins, and in recent times even found ways to speed up the natural toning process which would therefore still look like normal toning but didnt take the normal amount of time. Finding normal coins like you did in a typical roll suggests strongly that it is just a normally toned coin. Its mainly finding these from sellers who may have directly or indirectly been involved with some of those things in order to make a profit, and unfortunately sometimes its hard even for the experts to tell whats 'questionable color' or not.
