  1. As Art was saying, the modern sets are realtively easy and some can be completed from change/postal vending machines. If you don't need registry sets, and can live with circulated coins some ideas: Jeffersons from circulation - See how many you find in a year or two. You can buy the few extras. Circulated Frankling Halves would be another series with no big money key dates. A world coin birth year set is another, usually inexpensive, option for those of us still living. Or, if you can, just ignore the key dates. They can be a pain and exist in almost every series from Lincolns to Morgans.
  2. Thanks Mike. There are a few others who think like you do, but only a few dozen and they've all ordered a copy The E-sylum members seem to be the most interested bunch if I go by interest per group. Anyway I appreciate the comments from those who enjoy these volumes as much as I do. At least I know I'm not alone.
  3. Stujoe, It's the first six volumes. They are the most rare. The next ten are scarce, and from then on most issues aren't too hard to find. It's just that with very few members at the beginning very few issues existed. I think there's 12 original sets, the are tracked on the ANA website. You can email me numismatist@ancientcoinvalues.com if you are interested and I'll send you the paypa email address.
  4. Your are correct, I am just demonstrating some evidence that silver coins varied by measurable amounts since at least the 1930's. For clad coinage the exact weight is pretty irrelevant except that over billions of coins that scrap metal costs probably add up. I think the tolerances were much tighter on the big bags of coins released (in % terms) compared to teh individual coins. Personal weighing of coins probably lasted well into the 19th centuries in many if not all countries that used precious metal coins.
  5. Interesting stuff, I recognize some of the things from NIM-B. Manfred Schreiner also did analysy on some the the Sasanian coins in the new SNS put out by the Akademie in Vienna. He's also done other testing. It does appear that this site is violating the international copyright laws however . I know I have to pay about $30 to get access to the NIM-B articles and most of the articles appear recent and it seems doubtful the web host acquired free redistribution rights.

  7. O.K When I measured some Washington Quatrers from an XF-BU roll I got these results Coin # Avg Wt (g) Avg Wet Wt (g) SG 1 6.283 0.61 10.3 2 6.17 0.607 10.2 3 6.193 0.593 10.4 4 6.123 0.597 10.3 5 6.247 0.62 10.1 6 6.203 0.617 10.1 7 6.143 0.597 10.3 8 6.21 0.603 10.3 9 6.147 0.597 10.3 10 6.09 0.587 10.4 11 6.177 0.6 10.3 12 6.087 0.6 10.1 13 6.37 0.627 10.2 14 6.237 0.61 10.2 15 6.16 0.6 10.3 16 6.217 0.61 10.2 17 6.19 0.597 10.4 18 6.14 0.603 10.2 19 6.2 0.603 10.3 20 6.107 0.597 10.2 21 6.13 0.6 10.2 22 6.097 0.593 10.3 23 6.303 0.62 10.2 24 6.297 0.613 10.3 25 6.27 0.607 10.3 26 6.302 0.617 10.2 27 6.267 0.607 10.3 28 6.137 0.602 10.2 29 6.117 0.6 10.2 30 6.183 0.6 10.3 Avg 6.193233333 0.604466667 10.24658135 My set up does have some margin of error but I think it's save to say that for single coins +- .1 grams (stated weight is 6.25) is quite normal for 1932-1964 silver US quarters.
  8. Yes, the choices are tough. Perhaps Google will find some of the truly rare books and reprint them. I like auction catalogs for certain purposes, but a lot of the common stuff does get repetative. The ANS journals intrigue me, especially the works of E.G.Caley. Actually, all but one of his works on metrology of ancient coins should be in the public domain. The good news is that we are going to be able to access ever more information more easily and quickly than ever before.
  9. Yes like that, but with a better interface For me some ancient catalogs from the 40's and 50's woule be great to see. The stuff from the last 5 years or so is mostly online allready and pdf's can be downloaded from the dealer's sites.
  10. As I look, as I guess not too many. Sometimes I get email and Moneta confused as well. I think Zach of Beast coins would be one other who does appear in both now that he's half of a column in the Celator. A lot of the posters on Moneta-L deserve consideration for special mentions and awards. There are some truly thoughful and interesting responses. There's a few more on some of the speciality lists. My first nomination would have to go to Edward C. D. Hopkins the moderator of Parthia-L and creator of http://www.parthia.com. His website is truly a model, one I consider the best on ancient coins to date.

    Counterfeit Coins

    There are a lot of things to look for and a lot of variation in the quality of counterfeits. Weight is one of the most basic examples. If the weight is wrong (that varies much mroe for ancients thna for moderns) the coin is almost certainly fake. Diameter, specific gravity, color, and composition are other physical chacteristics that can condemn a coin's authenticity. Next would be signs of casting. The most obvious tends to be the seam, which is either present or has left some tell tell file marks. Although some are good enough to require a miscroscope to detect. Eventually, there are the really good fakes. Some of these require that you know the characteristics to detect. Even the best fakes tend to copy a die or an existing coin. So certain marks will appear over and over. If the counterfitter released only one fake it may never ge caught. But as multiple coins with the same marks appear the coins are dianosed, reported, and can be detected. The PCGS guide is a good read on this subject. If you want to go all out I am told from many sources that the ANA sumemr seminar is outstanding.
  12. On quarters it was a few tenths of a gram. I discovered this when calibrating my specific gravity measurement device. All the coins were of good silver but there was a noticeable if not large variation. I believe the exactness came more in bulk than in individual coins. Each $1000 worth of silver would have a very strict tolerance in percentage terms while an individual coin could have a little more leeway. I have the numbers on my other machine, I'll post them tonight.
  13. Danke, eine gute Seite fuer mich. Wenn ich reich werde weiss ich nun wan nack Berline und Muenchen zu fliegen
  14. What type of nline information do you could have access to? Scanning old magazines and articles or Seeing old auction catalogs?
  15. One could probablly do old catalogs relatively easily, especially if there's no need to make the text searchable, just page after page. For newer stuff, like anything else, copyright law can be a pain especially when the holders are long gone. Sometimes I wonder if having the Numismatisst Vol.1-6 be downloadbale could be offset by Google ad revenue. Probably not by itsself, but downloadable scanned material might be content that would draw more traffic.
  16. You write online and in print. Some of the Celator columnists also post, at least on Moneta-L do varying degrees. And of course your buddy Reid, he has written a few in print articles and certainly is active online I'll have to think about my favorite online writer and PM you.
  17. I don't think it is too unlikely that a Carthaginian or Roman vessel could have made it across the Atlantic. But, I do doubt that there was any purposeful or regular occurrence of such events. More like shipwrecks and lost crews. It's hard to imagine that regular contact would have been lost to the historical record.
  18. Berlin in February. That sounds only slightly warmer than it is here. Plus I can go to NY in January. If the Cologne show was a month later Ah well, we'll be mostly chatting with the relatives. Since I can't go to Vienna I think Hamburg and Berlin, maybe Aachen this time around.
  19. What are the major coin shows in Germany? Are there any good websites listing them?
  20. I'ms ure some will like it but I'm with you. It looks a lot like our state quarter clip art. I do prefer cohesive designs.
  21. Naturally, from schoolyard bullies to local gangsters, all the way to nation states. Human behavior is fairly predictable in most circumstances. BTW I have it on excellent authority that, "tenth century English pennies would be a refreshing subject" for publication in a certain magazine. I'm sure 9th and 11th would be fine as well
  22. So where the sceats not silver then, and how did they begin? Have you ever read The Pound by David Sinclair? It's a really basic overview of English coinage history. It read well, I'm just wondering if it's decent for an overview.
  23. I've planned quite a few vacations around coins. When I was single the summer ANA city would always receive a visit from me. I think my wife was six months pregnant with our first child at the Spring show in Jacksonville. I met my sister in NYC during the ANA there. Chicago is an easy sell to my wife (and someplace we can get to in a car). I figure a major coin show is as good a reason as any to visit a city. Though flying with four people doesn't warrant the expense. So, the Chicago international is more like a long weekend get away. I will likely be in Germany for two weeks in October, I won't stop at Coinex but if I see any decent shows I might go. I do usually at least find a shop and buy a proof set or something similar.
