Dear List, I was browsing through the latest VAuctions listings, and noted Greek coins termed "nomos". I don't recall seeing this denomination mentioned...
Hi Priscilla, Essentially, it is a didrachm and the term is used for Italian didrachms. Sometimes, "didrachm" or "stater" is also used for these coins...
There are some ancient inscriptions from that region that use the term "nomos" in reference to payments, and some people have taken it to mean the payments...
If anyone has current contact information for Michael Mitchener, could you please let me know off list. I'd like to get in touch with him. Many thanks in...
Hi all, One of the problems of being a modern person dealing with the things of the past is that we project our present onto the past without even thinking too...
Hi, Pierre/List I fear that I am a Saint Thomas (not for saint, but for Thomas), but I see no reason to beleive that this die is ancient (maybe old, say 20th...
... One has to be very careful interpreting his results. It is important to note that he states he could not effectively strike coins cold with his 3.5 inch...
http://www.cngcoins.com/Coin.aspx?CoinID=145036     JUDAEA, Bar Kochba Revolt. 132-135 CE. AR Zuz – Denarius (18mm, 3.41 g, 6h). Undated issue (year...
Unfortunately CNG imaged the obverse of the coin upside down. What they describe as the "lower cluster of grapes" is correct except on their image it is shown...
Roger, The velocity of sound in iron is 4910 m/sec or 193,306.7 in/sec. Thus, the impulse of a blow struck by a hammer on the end of a 7 inch long iron die ...
Dave, Surely from a purely momentum perspective, the amount of (kinetic) energy being dissipated by the flan should be the same in either case. If we consider...
The projectile theory of coin striking is popular but wrong, for the simple reason that the die isn't knocked onto the flan by the hammer, but rather is...
The striking of coins is completely and accurately described by the physical sciences. It has been known for many hundreds of years (certainly at least since...
The fact that the die is initially in contact with the flan makes no difference to the law of physics, neither does how far it travels after it is hit...
Dear List, In previous discussions about this topic someone recommended a paper by an archaeology student named Di Hu. He made his own dies and struck coins...
Dear List, All this talk about hot or cold striking of coins, furnaces in Roman mints, one or two men striking coins, etc. encourages me to throw an old...
John --  I don't usually take the time to carefully read long posts. This informative and interesting post is one of the rare exceptions.  Thanks for...
Going analytical to describe coin striking is probably a good thing. Since momentum and energy are both subject to conservation laws (and are quite different...
To my eye, I think it is clear this is a depiction of a goldsmith workshop. The cupid standing directly in front of the kiln is using tongs to hold an object...
Robert A. Heinlein, in his 1973 book Time Enough For Love, said : "If it can't be expressed mathematically, it's not science, it's opinion." Both Dave Welsh...
... No - that would only be the case if the hammer came to a stop and the die alone continued forward. In this case the hammer and die are going to both...
... Wouldn't the practice of the ancients tend to explain what was efficient for their process? The Roman switch from aes grave to struck bronzes would...
I have noticed the bulk lots that are sold by various auction houses like Baldwin's, VAuctions, CNG etc. and was wondering what was the deal with these coins....
Thinking through this... When it's mentioned, the line at Athena's neck on classical and intermediate style Owls is almost always described as a necklace, ...
I think Reid is correct about this, in that the beaded "necklace" on the Athenian issues is probably the upper edge of her breastplate, just as the beading...
Good questions. No seller would choose for their coins to be sold in a bulk lot. It is the auction house who chooses, because it cuts their costs. Otherwise it...
... being dissipated by the flan should be the same in either case. It is not. The amount of energy dissipated depends upon several variables, including the...
... This is incorrect. The correct expression is h*vh1 = h*vh2 + d*vd2, where vh1, vh2 are the velocities of the hammer before and after striking, and vd2 is...
Dr. Scott Rottinghaus, who's primary numismatic focus is on ancient coins and who has been a contributor to Moneta-L, has won his bid to be an ANA Governor....
