Really, when it comes down to it, most people aren't even going to bother. Yes, sure, it -sounds- like an easy way to make lots of money, but that isn't how it is in reality. It's really easy to read a few posts of people getting 15 skunk boxes in a row and think that it isn't too bad... But actually experiencing a skunk box for several weeks in a row will discourage all but the most persistent CRH-ers. Plus, as of now, the only outlets advertising CRHing are targeted towards metal detectors and coin collectors, people who, no doubt, know of CRHing in at least a rudimentary form (for example, if you see that a teller has a Peace Dollar or a Walker, you buy it) and know that 1965-70 coins are 40% silver. The only things that would be new revelations to them would be the techniques (such as dealing with large volumes of coins, dump banks, dumping out of district, etc.) for going through coins on a very large scale.
Really, the vast majority of people are
--deleted-- of our coinage. I'm sure we all as CRHers have had experiences where a cashier didn't know what a half dollar was. And we enjoy our hobby because people don't know what their coins are worth. I don't think that this is going to change anytime soon.
