What really concerns me about these cretins is that they will put new collectors off the hobby with their dishonest and criminal behavior. Once these new collectors get stung that is normally all that is needed to turn them of this great hobby and we will loose an up and coming numismatist, Just because there are a minority of ratbag sellers out there
Do people honestly think the AFP or likewise are going to do anything about it. My money is on them not giving a crap about someone making bottle top impressions on demonetised coins when they have other things to contend with eg. those fake $1 coins from china. Dont get me wrong what they are doing is vlearly wrong, preying on unsuspecting people but in comparison its likely not to get any attention.
The difficulty in prosecuting this guy with any sort of statutory offence is that proving that he actually defaced/mutilated/changed etc the coins. It's in all probability that he did, but in a court the burden of proof is "beyond all reasonable doubt".
It doesn't fall under state jurisdiction, & would be referred to the AFP for investigation. They would only look at this guy if he was counterfeiting.
Having said that maybe a course of conduct ie his eBay history, might spark an investigation.
