I knew it was bad luck when I did it, and that's what it turned out to be: the very next day, I got a notice saying that the seller had canceled the sale because the coin was "no longer available." Presumably he sold it and forgot to mark it as such on VCoins. So I looked around some more, on VCoins and elsewhere, and ordered a different coin that arrived today. So it's safe to post about it, and I'm actually happy that the first purchase fell through. Because I think this coin is considerably nicer, plus it shows both Diadumenian and Macrinus. And also happens to be my first coin with Hermes (or Mercury) on it. Macrinus and Diadumenian Caesar, AE Pentassarion [5 Assaria], 217-218 AD, Marcianopolis Mint, Moesia Inferior (Pontianus, consular legate). Obv. Confronted heads of Macrinus, laureate, right, and Diadumenian, bareheaded, left, [AVT K OΠE]Λ CEV MAKPEINOC K M OΠEΛ ANTΩNEINOC [bracketed portion off flan][= Imperator, Caesar, Opellius Augustus Macrinus, Caesar Marcus Opellius Antoninus] / Rev. Hermes standing facing, head left, holding purse in extended right hand and caduceus in left hand; chlamys hanging over left arm; E [mark of value for “5”] in right field, VΠ ΠONTIANOV MAP-KIANOΠOΛEITΩN (ΩN ligate) [= Consular Legate Pontianus, (coin) of the people of Markianopolis]. AMNG I/I 740 [Behrendt Pick, Die antiken Münzen von Dacien und Moesien, Die antiken Münzen Nord-Griechenlands Vol. I/I (Berlin, 1898) at pp. 240-241]; BMC 3 Thrace 35 [R.S. Poole, ed. A Catalog of the Greek Coins in the British Museum, Vol. 3, The Tauric Chersonese, Sarmatia, Dacia, Moesia, Thrace, etc. (London, 1877) at p. 32]; Hristova & Jekov 18.104.22.168 [Nina Hristova & Gospodin Jekov, The Local Coinage of the Roman Empire - Moesia Inferior, I - III c.

(E to left) [Ivan Varbanov, Greek Imperial Coins And Their Values, Volume I: Dacia, Moesia Superior & Moesia Inferior (English Edition) (Bourgas, Bulgaria, 2005)]. 25 mm, 12.89 g. Ex: Dr. Paul Rynearson (ca. 2003); Ex: Kirk Davis, Cat # 75, Fall 2020, Lot 62. It's lucky for the coin (and for me) that the compass points -- or whatever the technical name is for the small, shallow hole in the center of each side -- just missed Macrinus's nose, although they did get poor Hermes right in the belly. Apparently Paul Rynearson was a well-known dealer at one time, as well as the author of an introductory book on collecting Greek coins, but I confess I hadn't heard of him until I looked him up on Google. The reason I boldfaced the catalogue references to Varbanov and to Hristova & Jekov is that I wasn't able to check them personally, and am hoping that someone might be able to do so for me. In the majority of the examples I found online for this basic coin design from Marcianopolis (Macrinus & Diadumenian on the obverse with Hermes on the reverse) -- and there have been surprisingly few of them sold at auction in the last 15 years -- Macrinus and Diadumenian are each draped and cuirassed. The catalogue references for the minority of coins I found that are like mine, with only a bare head for Diadumenian and a laureate head for Macrinus, were mostly incorrect and erroneously referred to the draped and cuirassed type. I was able to find and/or confirm the correct AMNG I and BMC references -- as ancient as they are, both catalogues are still very useful! -- but I don't have access to Varbanov or to Hristova & Jekov. Does anyone here have either of them?
