"Bruce Remick" wrote in message ... Funny, too, you started off claiming that "someone" (wink. wink.) couldn't understand how whizzing causes metal to liquify. Then you changed that to "metal moving". Scratching a coin with a knife causes metal to move, which few likely would dispute. That the metal becomes liquified in the scratching process would take more convincing. Why is this so important to you to resurrect it at every opportunity? Because he is a lonely man with no friends, probably due to the fact that he is a condescending blowhard. |

Numismatist on whizzing
Forgive the top-post. It's called for here.
For heaven's sake, Reid, do I have to go through your whole post, point-by-point to demolish your silly contentions? Again? If you want me to provide evidence (*not* uninformed hearsay) for each point you have raised, then I will - but I sincerely doubt that you will read my reply. I also doubt that you have the capacity to understand basic metallurgy, as demonstrated by the howlers you have invented below. Here's an alternative set of suggestions: (1) Take your arguments to an independent qualified professional metallurgist. Ask for comment. Don't forget to mention the term "wire brush" - not to be confused with hardened steel die or knife or scraper. For additional hilarity, quote your much-vaunted PCGS "expert", and refer to an "electric screwdriver" as the motive source. (2) Look up "plastic" in a technical dictionary. cf. "solid", "liquid" and "malleable". (Helpful hint: "plastic deformation" as a search term will bypass a lot of the dross.) Thank you, at least, for coming out with your screed below. It firmly sets your position in this "debate" - something which you have not been willing to do in the past. It is certainly one for the permanent file. Further, it makes any more argument pointless, since your position is unassailable - one of faith and a complete lack of understanding of the simple processes involved. I don't like this analogy, but if you were a first year engineering student, I would fail you on the basis of this nonsense you have propagated. ....and finally, thanks for the flame at the end. As if it were necessary, it cements my position, and your attitude. Jeff "Facepalming" R. "Reid Goldsborough" wrote in message ... Reality wrote: Who cares about needless "science" when the coin either has or hasn't been whizzed? Science is only needless if you're not curious about the reasons things are as they are. You know, reality, Reality. Nice handle. In centuries past people would chalk up the reason for reality being the way it is as God's will. In ancient Greece and Rome most people believed it wasn't just one god that caused reality to be as it is but many. Now we know that there are underlying laws of nature that account for the physical nature of reality. Many people find learning about those laws interesting. This applies as well to numismatics. To recount ... this discussion came about when a single person here couldn't understand how applying a rotating wire brush to a coin's surface, i.e. whizzing, could cause a thin layer of surface metal to heat up enough to become a thick liquid and move. He disagreed with the science behind this being possible. He has a metal shop, and he fashioned an experiment to prove his point, not to learn about the reality of the situation, but to prove that he was right. This metal shop whiz tried to whiz a coin in his metal shop to cause the metal to move. Alas, he wasn't able to. No moving metal! So he concluded that he was right, that whizzing doesn't move metal. To support his case, he fashioned a pseudo-scientific explanation, diagrams and all, and put it on the Web, so everybody could become edified by his scientific experimentation. And some people here were, frankly, snowed by this. They were taken in by his "tone" and apparently continue to be. One of the things I'm fairly good at, one of the things I have to be good at to do my job, is recognizing when people are playing expert. There were many problems with the experiment of the metal shop whiz. First, he had a point to prove so he had some bias from the outset. Second, he admitted he had never seen a whizzed coin before trying to create one. Third, he didn't talk to anyone who whizzed coins to learn what they did. Fourth, as we've just learned, he used the wrong kind of metal brush in his "whizzing" experiment. Fifth, he can't credibly explain the diagnostic of whizzed coins, which he was unaware of before doing his experiment, that metal from a coin's fields shows evidence of having been pushed up against devices, legends, and rims, that it has moved. Sixth, in arguing that metal is removed, not moved, in whizzing, he can't credibly explain how the diagnostic of whizzed coins isn't weight (because the weight of whizzed coins is the same as unaltered coins, at least to two decimal points, and weight is never mentioned as a diagnostic in books or articles that address the subject of whizzing). Seventh, the most visible coin doctor in the U.S., a guy who has whizzed his share of coins even though these days whizzing has fallen by the wayside as a convincing coin-altering technique, says that yes, whizzing moves metal. Eighth, those who have seen their share of whizzed coins, the ANA, PCGS, and NCS, no doubt among many others, also say that yes, whizzing moves metal. The science behind this -- real science now, not pseudo-science buttressed by fancy-sounding jargon and wrong-headed experimentation -- is interesting. Just as metal turns into a thick liquid and flows when a coin is struck and just as metal is moved, not removed, when a coin is countermarked or when in ancient times a coin was test cut, so does a thin layer of metal turn into a thick liquid and move when a quickly rotating wire brush is applied under pressure to a coin's surface in the process of whizzing. The force applied causes enough heat to melt the surface metal enough to move it in the way desired. As happens online all too frequently, the metal shop whiz has refused all along to admit he could possibly be wrong. "Internet experts" are never wrong. To admit a mistake or to change one's view would be to lose face, in their minds. The evidence against his position is incontrovertible. Yet he continues to argues his position, that whizzing doesn't move metal. I see, Reality, that you acknowledge that whizzing moves metal. So maybe Reality is a good handle after all. In conclusion, I believe that this metal shop whiz is a dodo. I'm not being dramatic here or trying to flame or anything else. I really think that he's a dodo, not a human being at all, and that perhaps he may be the last surviving dodo on the planet. Beyond the silliness of this continuing debate, this is what's truly newsworthy about all this. -- Consumer: http://rg.ancients.info/guide Connoisseur: http://rg.ancients.info/glom Counterfeit: http://rg.ancients.info/bogos |

I will probably regret this, but in daring to enter this discussion at this late stage let me say that "whizzing" arose in the early 1970s when battery-powered, pen-shaped, electric-eraser-like polishing tools came on the market. One of the tool heads was a small wire brush, intended for home hobbyists. Now the way to tell whether a (silver) coin is uncirculated is to look for unbroken mint lustre. If a coin is only AU, slight flatness can be seen on a high spot or two. Many AU Mercury dimes, taken from circulation, were available in the 1970s, and would be worth quite a bit more if they could be sold as BU. Unscrupulous persons took these dimes (later, Morgan dollars and anything else) and used these electric brushes--the name whiz comes from the sound the brush made--to obscure the flat spots on these dimes with a pattern of fine scratches that simulated original mint lustre (though not very well). Tip one of these whizzed dimes around, and, at a glance, it looks BU. It is certainly true that no significant amount of metal is removed by this process (the coin is given the briefest "whiz" by a whizzing artist); it is merely scratched up a little. But there is no chance that these little battery-powered tools could possibly heat silver up to its melting point either; this is surely a misunderstanding. Unfortunately, the term "whizzed" has lost its original meaning in the intervening decades, and possibly some coins polished with high-speed equipment could actually become red hot and partially melt. Also, hairlines have been removed from the fields of cameo proof coins by localized melting in recent years, but I think that this is done with lasers. In my opinion, calling polishing/localized laser melting "whizzing" is a misnomer, and distracts collectors from checking their shiny Mercury dimes or other "BU" coins closely. I hope that this little explanation adds more light than "heat," and that no rcc reader discovers a whizzed coin in their collection! |

We (at least most of us) can spot a whizzed coin from a mile away and would never buy it beyond a modest premium over spot metal. Or in the case of a truly rare coin, with a MAJOR discount applied. |

The only MAJOR discount I've ever seen for a problem coin is when the dealer is offered one by a collector. In the other direction, it's always just a small percentage below fullbore retail. But that's just my experience, based on half a century of doing coins, so others may see things differently. James |

I've owned a few whizzed coins over the years, bought as Unc and later revealed as "enhanced". From what I gather, the whizzing tool or brush can create enough micro-swirl ridges to increase light reflection/refraction and give the false impression of lustre to the naked eye. Unfortunately there have been a lot of naked eyes out there. |
