|Volume 46 No. 5||May 2000|
My notes about digital cameras last month convinced me to purchase a nice digital camera. Come to the May meeting, and see what results from ten days of self-study with an owner's manual. Color pictures will be taken of the coins brought in for show-and-tell, and they will appear in the web edition of the Chatter. Some of the images will be used in the printed Chatter edition to fill out the pages.

The 975th meeting of the Chicago Coin Club was called to order at 1:10 PM, Saturday, April 8, 2000, by president Carl Wolf at the Ramada O'Hare during the Chicago International coin Fair. This meeting was in 2 sessions with the second session to be held April 12, 2000, at Bank One Plaza. Carl spoke briefly about the current CICF giveaway as well as future souvenir sheets.
First VP Steve Zitowsky then introduced our featured speaker for the afternoon, David L. Vagi who spoke on New Perspectives on Ancient Roman Coins. David showed the family tree of the Julio-Claudian dynasty, and presented a slide show of coins depicting members of the families of the 12 Caesars. After a brief question and answer period, Steve presented the ANA educational Award and the CCC Featured Speaker Award to Mr. Vagi.
Carl presented the other officers of the CCC to the audience as contact people for questions about the Chicago coin Club such as becoming members and past and future activities. Special guests were introduced; Cliff Mischler, Bill Bright, John Wilson, and Kermit Wasmer.
At that point Kermit Wasmer made the presentation of the ANA Presidential Award to Mark Wieclaw for all of his efforts as speaker and leader in furthering numismatics. Members and audience gave Mark a round of applause.
There was a first reading for membership in the CCC for Satya Bhupatiraju, Mike Schmidt, and Russell Wajda.
Bob Leonard spoke briefly about the current CICF souvenir sheet which he wrote. Carl made the usual presentation of the souvenir sheets with #1 going to the club archives, #2 going to the featured speaker, #3 going to the author. At that point the first session was recessed and the souvenir sheets were distributed to all in attendance. Meeting dispersed at 2:45 PM.

Author and dealer David Vagi addressed the session of the April meeting held in conjunction with the Chicago International Coin Fair, on April 8, 2000. Having recently written the two-volume Coinage and History of the Roman Empire, David showed us some of the new ideas regarding the coins of the 12 Caesars and that era. New perspectives emerge not only from archaeological discoveries, but also from the critical reexamination of existing knowledge.
David started this talk where he had left off a few years ago during his previous talk to us at CICF; with Brutus, one of the murderers of Julius Caesar. That talk was well-received owing to his lively presentation tieing together the usual and unusual historical facts along with some pithy comments regarding some tidbits of scandalous gossip. The audience this time was treated to his first pithy comment soon after David displayed the dynastic tree of the Julio-Claudians, where intra-family murder was more common than intra-family marriage.
Many collectors of Roman coinage search for coins that can be tied to a particular person (usually of the royal household). A coin might honor that person, be issued by that person, or might show that person without an explicit identification being given. One of the more popular and rarer Roman coins is the EID MAR denarius bearing a bust of Brutus and his name (BRUT). That coin is expensive due, in part, to the small number available. The next slide showed a coin with a very similar bust, struck in 41 B.C., but with the name of the moneyer Lucius Servius Rufus. David mentioned that the bust is generally (about 95%) accepted to be that of Brutus, and this coin is more available and less expensive than an EID MAR denarius.
The coins from the provinces showed a wider range of people than were shown on coins from Rome. Mention was made of a provincial coin bearing the bust of Augustus' librarian.
Actual women were sometimes pictured and named on coins, but sometimes there would be only an allegorical legend. Livia, the wife of Augustus, appeared on many provincial coins but on few Imperial coins. It is accepted that the bust appearing on a bronze dupondius bearing the legend SALVS (health) AVGVSTA is of Livia, but the other two dupondii with the same reverse style are thought now to honor others. The dupondius with the legend PIETAS (piety) is conjectured to honor Livilla, the wife of Drusus whose name appears in the reverse inscription. The dupondius with the legend IVSTITIA (justice) could honor either Antonia or Agrippina Senior, because this coin could have honored the justice meted out by the execution of the alleged murderer of Germanicus; Antonia was his mother and Agrippina Senior was his wife.
The hypocrisy in the above use of the legends piety and justice was brought out when it was mentioned that the father of Livilla's twin boys was rumored by many to be the Praetorian Prefect Sejanus, who would later be considered to be the true instigator of Germanicus' murder (but only after Sejanus had Drusus murdered and Sejanus' plot to take over the empire became well-known). That first slide showing the Julio-Claudian family tree was needed by the audience to keep everything straight.
David mentioned a few other Julio-Claudian people who are hard to find on coins before discussing the family of Vespasian, the start of the Flavian line. The difficulty here is with Vespasian's wife and daughter, both named Domitilla, and both dead before Vespasian became emperor; so their issues are memorials. Some sources give all coins to Domitilla the Senior, while some give it all to Domitilla the Younger. David explained which coins he believes honor which woman.
David answered a few questions from the floor, and then remained available for questions after the meeting broke up.
The following talk was presented to the club by Don Dool on April 12, 2000.
To begin with this is not going to be a highly technical talk on Electron Microscopy or X-Ray Analysis. While I will include a brief technical rundown of how it works I will focus mainly on why and how I became involved in the subject, test results of a selection of coins and what conclusions, if any, can be drawn.
As most of you know I have a collection of AD dated copper and bronze coins and occasionally I let a brass one in. Billon is out even though it is mostly copper. I consider a billon coin to be a government issued counterfeit and as such I prefer contemporary counterfeits. For this reason, over time I had acquired among other things several coins that are supposed to be silver but look to be copper.
About a year ago I made contact via an ebay auction with a numismatist named Tom Pesacreta. Tom had a coin listed that neither of us had any reference material for and I questioned him about the metallic composition. As luck would have it he is a biologist at the University of Louisiana in Lafayette and is in charge of a laboratory with an electron microscope. He ran tests on the coin and found it to be copper. Unfortunately I neglected to place a bid on the coin and missed out on it. I had told Tom about various coins in my possession that were apparently off metal and he offered to analyze them. Tom mentioned that another way that people frequently use the scanning electron microscope for counterfeit detection is to examine devices for characteristic features. He also said that ancient coin researchers use the x-ray analysis for analyzing the elemental content of coins to determine which mines the ore was taken from. I assume this is also for the purpose of detecting counterfeits.
Now before looking at the coins and the test results a few thousand words on the equipment and how it works.
The equipment used is a JEOL, 6300FV field emission scanning electron microscope (SEM). Field emission is a non-destructive analysis method as opposed to the technique of x-ray diffraction. That is a technique very commonly used to analyze solid materials, but it is usually done with powders and is a destructive technique. The two functions of the SEM utilized here are imaging and elemental analysis.
Tom provided me with this elementary explanation of what happens within the subject coin. The x-rays are generated by so-called primary electrons that are focused on the sample by the electron microscope. These primary electrons are very fast moving and as a consequence, have high energy levels.
When a primary electron enters the sample several events can occur but we will pay attention to only two of them. The first event that can occur is that a very small amount of the energy of the primary electron can be transferred to a outer orbital electron in an atom. This causes the outer orbital electron to leave its orbit and it can then be used for imaging the sample.
The second event that can occur, and this is what enables the elemental analysis, is that the primary electron can come so close to an atom that it transfers a relatively large portion of its energy to the atom. In this case an inner orbital electron must be ejected from its orbit in order to let the atom return to its low-energy equilibrium state. The ejection of the inner orbital electron creates a temporary hole in that orbital and a high energy outer electron falls down into it. As it falls it releases a specific level of energy which is defined by the energy difference between the two orbitals. This specific energy difference is what you see displayed on the spectrum. The greater the initial difference between the two orbital, the higher the energy of the released x-ray. [The energy is on the horizontal axis of the following graph, and is expressed in units of kilo-electron-Volts. The atomic symbol for each element is printed next to its corresponding peak. Note that the symbol for copper (Cu) appears twice; some elements repeat at higher energy levels, but that part of the graph was removed to simplify the image. - editor]
As you can probably imagine, because of the specific differences in the number of electrons and protons in each element, each element has a complex but characteristic x-ray energy signature and a sophisticated computer program can be designed that can help the operator decide which elements are present.
Actually it is more complex, there are up to 4 shells of orbiting electrons in each atom and the electrons can jump from shell to shell.
Now let's move on to the coins and their test results. The coins that were tested were:
In addition to the above X-Ray analysis, an electron microscope also produces images. Here is the top half of the 5 digit on the piece from Cambrai. Note the second top flag and small part of a vertical stem.
Hard to find a conclusion. The coins are from completely different time periods, locations, and were acquired from three different dealers. No common denominators. My reasoning to a "conclusion" has been along the following lines.
For there have never to have been any silver on all of the coins does not seem valid if they are contemporary counterfeits and if they are not, what are they? Patterns, very unlikely. Or maybe modern counterfeits; but for the value of the coins, hardly worth the trouble. So I have to start with the premise that either they were silvered or the counterfeiters were able to pass copper coins, maybe, but again unlikely in all three cases. But if they were silvered to begin with, then why no silver now?
Since silver did show up on the billon coins, it is safe to rule out any possibility of faulty equipment or technique. Was the silver deliberately removed by some cleaning process? Again unlikely and why would anyone do that anyway?
So maybe the coins were silvered and because of the method of applying the silver it did not bond to the surface of the coin and wore or rubbed off easily. I would also assume that the amount of silver applied was as minute as possible. Now it is possible and maybe even probable that the same scenario does not apply to all three coins and there is no way to know for certain but I think that my hypothesis is the most reasonable.

The Board of Directors of the Chicago Coin Club was called to order by President Carl Wolf at 6:20 P.M. at the Hickory Pit Restaurant, 2801 S. Halsted. The following members were present: Steve Zitowsky, Robert Feiler, Mark Wieclaw, Paul Hybert and Michael Metras. Robert Leonard and William Burd were also present at the request of the President.
Following a discussion on printing the Club's Constitution, it was decided that a brief history of the Club should also be included and 150 copies printed. Carl Wolf volunteered to get printing prices and Paul Hybert took on the responsibility of updating the electronic version of the Constitution.
Carl Wolf announced that Channel 50 WPWR has contacted the Club. They're considering shooting a coin collecting episode for their program UP'N RUNNING and wanted to know if we have knowledgeable people who could be interviewed on this subject. Carl contacted the Associate Producer by telephone, volunteered our services and also explained the concerns members have with security, especially having their names and or faces appear on television. She thought it could be worked around and would get back to Carl.
It was announced that Robert Weinstein had begun film editing on the video project.
A long discussion was held on the subject of conducting an all day seminar with the 2001 Mid-American Coin Show sponsored by Krause Publications and held in conjunction with the International Collectibles Exposition, scheduled for June, 2001 at the Rosemont Convention Center. Bob Leonard spoke of his ideas and concepts. The resulting roundtable discussion showed no consensus favoring an all day seminar with in-depth talks held prior to the show or a series of general talks held the day(s) of the show. Bob Leonard was appointed to be the Club's point person on the project. He'll be contacting Krause Publications to get more information on their goals and plans.
Under the subject of general Club publicity, Paul Hybert received the support of everyone to post Club meeting notices on other reputable Web sites and mailing lists. The subject of having someone specifically in charge of writing publicity reports was discussed and several names were brought up. It was announced that Paul has a digital camera and intends to use it at upcoming meetings.
Carl pointed out that when Chicago area television and radio stations have questions concerning coins or coin collecting, their only available resource are coin dealers from the telephone book. He was authorized to compose a letter volunteering the services and knowledge of the Club's members. Mark Wieclaw volunteered to get a list of stations in the metropolitan area.
A motion was unanimously supported to donate a copy of the Club's Postage Stamp Money article to the American Numismatic Association, the American Numismatic Society, the Chicago Historical Society, the National Postal Museum and David Sundman of Littleton Coin Company for providing invaluable information.
The last subjects discussed were potential subjects and speakers for the December banquet and the possibility of having the board meeting's agenda e-mailed to the Board in advance.
The meeting was adjourned at 8:10 P.M.

Coinage of the Saka.
Saka was the name by which the Scythians refer to themselves. These were a nomadic people who are first mentioned in history in the 8th Century BC as raiders and plunderers of Greece, Persia, Egypt, and Assyria. They were held together by a common language and culture that reached from Eastern Europe to the borders of China. Within numismatics perhaps the most commonly known Scythian subgroup was the Parthians. Join Mr. Weinstein as he shares with members examples of the diverse coinage from these people (300 BC - 300 AD) and gives an update on the latest research in Indo-Scythian numismatics.
