You said
but it is an acid, so it needs to be rinsed with clean/distilled water (unless its copper)
Acetone is a solvent that won't react with metals or toning on coins.  Most/all will evaporate before you even get a chance to rinse in distilled water.  The only reason to rinse is if you use dirty acetone and it won't matter unless you are very, very quick.  A distilled water rinse doesn't hurt but it really doesn't help anything
Been using acetone for years and Freon before that, and have had no issues with not rinsing. But I usually do a double rinse and change it frequently.  
A little overkill for removing PVC plasticizer residue

 

I believe that the true collectors out there will educate themselves and try to acquire knowledge through books and other means of information as well. I think there are more true collectors than people think. They are just being overshadowed by the bombardment of treasure hunters looking for “the big score” and not worried about actually educating themselves.

I learned something the other day about CT. I always thought that two different users could not have the same IP address but they can. Something like a father and son can both work off the same PC with different user names.
Fun story from CT. Father and son both have accounts. Father gets banned for some reason. Son still keeps posting. Father tries to use sons account to post on the site. Both accounts are now banned. The writing styles gave them away.

Twist the laws anyway you wish. I see this type of coin as a counterfeit. On top of that the design is not his work. He is using someone else's work. 
With that said, I'm a big fan of Carr's original work but not garbage like this.
