I finally took the time to read this thread today. It's obvious that TypeCoin spent a lot of time and put a lot of effort into this, and I applaud his efforts. Learning how to correctly identify harshly/improperly cleaned coins is one of the hardest things there is to learn in all of numismatics. To try and put that into perspective I'd say this. If you think what has been written is complicated, try wrapping your head around this - TypeCoin has only scratched the surface of the subject. Please understand, I'm not defending the guy, (your dealer), but what I said above ties into this. The writing that TypeCoin did here requires 23 clicks on the page down button to get from top to bottom of what he wrote. So just imagine how much time it would have taken to explain all of that verbally. And no, I don't know what the situation was with your specific coin, he may have been able to explain it 5 or 10 minutes. But when two people start a discussion on a subject like this, it's almost never gonna take 5 or 10 minutes because as soon as he says one or two things, you're going to start asking questions. And with everything else he says, you're going to ask more questions. And each question requires answers, explanations. So that 5 or 10 minutes suddenly turns into a discussion that has gone on for 2 hours and you still haven't gotten anywhere. It's likely your dealer knows this because you can bet he's been in the same situation many times already. So rather than enter into that situation again, he says what he said. In other words, what he's doing is telling you it would take too long to explain. What folks need to understand is that what I said above about learning how to correctly identify harshly/improperly cleaned coin being one of the hardest things there is to learn in all of numismatics - well, even that is a gross understatement. If you ever take the time to look you'll soon find that there are no books on this subject. And I've always suspected that the reason there are no books written on this subject is because no single book could ever cover it, it would take several books. And it's hard enough to get people to spend money buy numismatic books as it is, let alone several of them just to learn about one subject. And writing a book is a whole lot of work and writing several is a whole lot more, especially if you consider that hardly anybody is ever going to buy them. And besides that books would not be the best way to learn about this subject, might not even be a good way to learn about it. That's because learning all this requires hands on experience, and a whole lot of time, years, many years. And in a way that's the what dealer referred to above was trying to say - that he spent most of his life trying to learn it. Overall there's a lot of of useful information in what TypeCoin wrote. There may be a few inaccurate conclusions or false assumptions mixed in here and there but for the most part it does a fair job of getting some basic information out there. And I'm not trying to find fault or be argumentative, not in any way, so please don't take this comment that way.
