lugburzman[at]yahoo[dot]com wrote: No one has yet brought up the topic of what is commonly called metal "chasing," a technique by which metal is moved around with various hand tools to form new letters and numerals. Among coppers, many fake 1799 large cents, the "1815" large cents, as well as the famous "altered reverse" large cents, are the result of the use of this technique. I will defer to others to determine if it has any kinship with whizzing. This actually is another interesting phenomenon, though different from whizzing. I actually picked up recently a 1914-D Lincoln cent that had been tooled from a 1944-D Lincoln cent, to study the process, which I know has happened with the coin types you mention as well as many others. I'm most familiar with the process with ancient coins, an area I've been most involved with lately, with scammers sometimes tooling coins to improve their apparent grade and other times to change them from a common to rare variety or type. I hadn't heard before the term "metal chasing." Interesting. A very quick Google search indicates it has legitimate metallurgical functions as well. Anyway, this tooled Lincoln cent is part of a cent set I'm building that goes back before cents to coins that directly preceded and most influenced it, to ancient times -- U.S. cent - British penny - French denier - Roman denarius - Greek drachm. I won't be able to include every type (no Chain cent for me), but it'll be representative. Mostly authentic official undamaged coins (sometimes different varieties of the same type/year) along with official damaged coins (holed, broken, corroded), official imitatives (sometimes called restitution issues), barbarous imitatives, contemporary forgeries, old "name" counterfeits, recent counterfeits, tooled pieces, modern marked replicas, modern unmarked replicas, and so on. Variety is the spice of collecting. g -- Email: (delete "remove this") Consumer: http://rg.ancients.info/guide Connoisseur: http://rg.ancients.info/glom Counterfeit: http://rg.ancients.info/bogos |

wrote: This is from the book Official A.N.A. Grading Standards for United States Coins: "A whizzed coin has been mechanically wire-brushed... The most important diagnostic is the build-up of metal on the coin's raised devices. As the wire brush moves across the surface of the coin, a microscopic layer of metal is liquefied BY THE HEAT produced by friction." (Emphasis mine.) The ANA continues: "The metal is pushed along in front of the brush until a raised device is encountered, upon which a ridge of metal is deposited." Gee, sounds familiar, doesn't it? Which version of the book is that? In the 5th, and the newly printed 6th I see the following, " Types of processing include polishing and ABRASION, which REMOVES metal from a coin's surface, etching and acid treatment, and 'whizzing'. The latter usually refers to ABRADING the surca eof a coin with a stiff wire brush, often in a circular motion, to produce a series of minute tiny parallel scratches which to the unaided eye or under low magnification appear to be like mint luster" Emphasis mine. Bottom line: Metal is moved. Not removed. With whizzing. Just as with striking. Based on the current ANA information I would read both as happening. Obviously the abrasion referred to above which leaves the scratches removes metal. Some of that builds up around letters and devices, which for my money can be defined as moved metal. I am curious with what revision the updated understanding was added. |

Just one. I'm not asking for multiple ones, as you're charging. Just one." No other parameters. a comment that was actually correct, not "ignorant." Only in your own little universe. ~Anka |

You accused me of offering up numerous ignorant comments, yet you quoted one in which I agreed with the authors of the two most widely used and respected grading guides in the coin industry. Were their comments ignorant too? When you say my comment was correct only in my own little universe, you're disagreeing with not only me but also the ANA and PCGS and agreeing with Jeff the metal worker from Australia. I can see that. -- Email: (delete "remove this") Consumer: http://rg.ancients.info/guide Connoisseur: http://rg.ancients.info/glom Counterfeit: http://rg.ancients.info/bogos |

wrote: I am curious with what revision the updated understanding was added. Your understanding of the "updated understanding" in incorrect. It wasn't updated. The same language appeared in both the 5th and 6th editions. Only you left out important information, specifically this sentence immediately following what you quoted: "Under high magnification (in this case a very strong magnifying glass should be used) the surface of a whizzed coin will show countless tiny scratches as well as metal build-up on the edges of letters and numerals." In other words, metal moves. It's not nice to leave out information like this. Is some metal abraded? No doubt, as I said earlier, some tiny amount of metallic dust, but so little that it's not measurable with the scales typically used to weigh coins, not to the second or third decimal point on a gram scale. That's really tiny. I also left out information, in what I quoted earlier from the ANA grading guide. I forgot to mention that the part I quoted was from a chapter bylined by Michael Fahey. This doesn't affect the truth of what I quoted like what Jorg just did, but I should have noted it. Michael Fahey is currently a grader for ICG and before that was a grader for ANACS, for 25 years. He's also a columnist for Coin World. Note that anyone can come to the same conclusions as Michael Fahey, the other authors of the ANA grading guide, and the authors of the PCGS guide by simply looking under a stereo microscope at a whizzed coin. Try it, you'll like it. Under such magnification the surfaces of untooled coins also reveal wonders unseen and unseeable by the naked eye. Different world, with cliffs and valleys like some alien landscape. -- Email: (delete "remove this") Consumer: http://rg.ancients.info/guide Connoisseur: http://rg.ancients.info/glom Counterfeit: http://rg.ancients.info/bogos |
