Benefactor KenDorney Posted June 20, 2022 · Benefactor Benefactor Share Posted June 20, 2022 This Ptolemaic coin is fairly low grade, but it exhibits a number of characteristics of ancient coin minting methods. Most prominently the lathe marks and the casting sprues from the blank planchet. Post your interesting coins showing minting remnants. 14 Quote Link to comment Share on other sites More sharing options...

Benefactor DonnaML Posted June 20, 2022 · Benefactor Benefactor Share Posted June 20, 2022 (edited) Thanks for this. @Roman Collectorand I gave these marks the name "lathe dimples" over in the other place, so as not to confuse them with compass dots a/k/a centration dimples. The best explanation of them I've seen is on the now-defunct classicalcoins website, which is fortunately still available on the Wayback Machine at https://web.archive.org/web/20210411064927/http://www.classicalcoins.com/flans1.html. (If you keep clicking "next page" at the bottom, or substitute the numbers 2 through 8 in the url, you'll see the subsequent pages of the discussion, all preserved at web.archive.org.) See also Butcher, Kevin, Roman Provincial Coins: An Introduction to the Greek Imperials (Seaby, London, 1988) at p, 67: "The coins [of Moesia Inferior] frequently have a small circular depression in the centre of the obverse and reverse, possibly the result of being clamped in a sort of lathe device used to smooth off the edges of the coin." Just about all of my Roman Provincial bronze coins from Moesia Inferior, as well as those from Thrace, have these "lathe dimples." Here are some examples: Edited June 20, 2022 by DonnaML 11 Quote Link to comment Share on other sites More sharing options...

Roman Collector Posted June 21, 2022 · Patron Share Posted June 21, 2022 (edited) This coin has a little bit of everything! It has two flan chips from where the sprue was broken off of the cast flan. It has a compass dot between the emperor and empress from laying out the design before engraving the die. It has a lathe dimple from flan preparation. It has doubling of the obverse from a die shift during striking. Gordian III, with Tranquillina. A.D. 238-244. Roman provincial AE 4.5 assaria; 28.92 mm, 15.89 g, 7 h.

Finn235 Posted June 21, 2022 · Member Share Posted June 21, 2022 I won a small lot of nicer Ptolemy bronzes a couple years ago, two of them had very prominent lathe marks This one additionally has visible file/lathe marks on the edge from where the flan was "edged" 8 Quote Link to comment Share on other sites More sharing options...
AncientJoe Posted June 21, 2022 · Member Share Posted June 21, 2022 Here are my two, the first of the Zodiac and second of Noah's Ark. Both are rare types and often come with these central alignment dots. I don't find them distracting at all. 8 1 1 Quote Link to comment Share on other sites More sharing options...

I'm not so sure cos good conditioned Thyrsos NewStyles have weights that vary in the reduced Attic weight "standard" For silver this level of quality control seems pointless when weights per coin varied so much. Gold is a different matter! 5 Quote Link to comment Share on other sites More sharing options...
