This fabulous picture was sold at Sotheby's last week for $187,500. It's from 1630 and he's taken a lot of care to depict the coins accurately. This would be a wonderful thing to hang in one's 'coin room'! Post your attributions, and any of these you have in your own collections.
Meant to include the link to Sotheby's catalog, with more details: http://www.sothebys.com/en/auctions/ecatalogue/2018/master-paintings-evening-sale-n09812/lot.38.html
The one in the middle is a tetradrachm from Thasos. Here's mine: Thasos, Thrace Tetradrachm Head of young Dionysos right, wreathed with ivy HPAKΛEOYΣ ΣΩTHPOΣ ΘΑΣΙΩΝ Heracles standing facing, head left, right hand resting on club, lion skin in left Monogram in left field 34mm, 16.82g Thasos c. 148-90/80 BC SNG Copenhagen 1040 ex-ANE "Hercules is the savior of the people of Thasos!"
I see a German bactreat in the front! I’m afraid I don’t know these well enough to ID without some serious searching
This is going to be fun! It will be interesting to see how true the artist was to the coins. Clearly he had real coins "posing" for the picture, but some of the details aren't quite right. The coins in the tray (1, 2, 3) are probably denarii, judging by relative size. The rest are Roman bronzes (sestertii and middle bronzes), Greek tetradrachms, and some later coin (#9, a bractreate?). Here they are with numbers for ease of people posting their guesses:
1-3 look like RR denarii, 4 is a sestertius of Pertinax, 5 is a as/dupondius with FELICITAS PVBLICA, 7 looks like a celtic imitation tetradrachm, 10 looks like it could be a As of Augustus Caeser, 11 is a DIVVS AVGVSTVS, a death commemorative of Augustus(?) and 12 is just some as/dupondius. 9 is a German bractreate, and the rest are greek silvers. (I'm not good with greek).
#1: Cassius Longinus denarius? CNG example: L. Cassius Longinus. 60 BC. AR Denarius (3.81 gm). Draped and veiled bust of Vesta right; kylix behind, S (reverted) before / Togate male standing facing, dropping tablet inscribed V into a cista; LONGIN III V behind. Crawford 413/1; Sydenham 935; Cassia 10. EF, partial flat strike.
#2: Q. Titius denarius CNG example: Q. Titius. 90 BC. AR Denarius (18mm, 4.10 g, 3h). Rome mint. Head of young Bacchus (or Liber) right, wearing ivy wreath / Pegasus springing right. Crawford 341/2; Sydenham 692; Titia 2
4. Septimius Severus sestertius... although I bet it's really a Paduan medal, like this CNG example: Septimius Severus. AD 193-211. Cast Æ “Sestertius” (40mm, 36.91 g, 12h). By G. Cavino (1500-1570). L · SEPTIMIVS · SEVERVS · PERTINAX · AVG · IMP VII, laureate and cuirassed bust right / CONG II DAT POP, Severus seated right upon pile of arms, holding patera over modius filled with grain ears; to right, Genius standing left, holding torch and cornucopia; S · C in exergue. See I. Prokopov ‘Fake Ancient Coin Reports: Work of Known Forgers,’ no. 131 for a similar example. Good VF. Excellent workmanship. A very early cast Paduan medal.
What is #6 trying to be? Some sort of AR of Cleopatra VII? It's not ringing a bell and the legend, as painted, doesn't make sense. One of the Ptolemaic women...
#2 could also be this version of Q Titius, if not the one posted above Roman Republic, AR Denarius(18mm, 3.83g, 8h). Q Titius, moneyer, 90 BC, Rome mint. Bearded head(Mutinus Titinus?) right, wearing winged diadem. Line border / Pegasus right; below, in linear frame, Q·TITI. Line border. Crawford 341/1; Sydenham 691; RSC Titia 1; BMCRR Rome 2220; Russo RBW 1274. And #3 is possibly this one: ROMAN REPUBLIC. Anonymous. AR Denarius Rome Mint, 86 BCE. Obv.: Laureate head of Apollo right; thunderbolt below. Rev.: Jupiter driving galloping quadriga right, hurling thunderbolt and holding reins. Reference: Crawford 350A/2 #7 and #13 look like Celtic imitation coinage....with #13 possibly being a Philip II of Macedon imitation.
Did you go to the viewing? I saw it in London when it appeared at Bonham's, without attribution. It was widely admired and recognised, and smashed the estimate.
