There is a tight series of gold issues from Pyrrhus’ arrival in Tarentum (HN Italy 983-992). They share common controlmarks and are signed by the same magistrates. A variety of denominations are known: stater, 1/2 stater, 1/4, 1/3, 1/8, 1/10, 1/12, and 1/16. A variety of dieties appear on the obverse, Zeus, Apollo, Athena, Heracles. The reverses types include a biga, a dolphin rider, a biga of dolphins, an owl, and on three denominations an eagle, such as that illustrated above.
This eagle bears much in common with an eagle to appear at the end of the century on Roman gold:
Here is a link to a variety of illustrated specimens of the Roman issue. When writing about this issue Meadows has made a very strong case that the iconography reflects Ptolemaic support. I give only a little quote here (1998: 128):
Could it mean the same thing at Tarentum? I think it very likely indeed. Hammond 1988 makes a strong case that the Ptolemy that sent military aid to Pyrrhus for his campaign in Italy was Philadelphus base on this portion of Justin:
11 Nor was Pyrrhus of Epirus neglected by him, a king who would be of great assistance to whichsoever side he attached himself, 12 and who, while he desired to spoil them one by one, sought the favour of all. 13 On going to assist the Tarentines, therefore, against the Romans, he desired of Antigonus the loan of vessels to transport his army into Italy; of Antiochus, who was better provided with wealth than with men, a sum of money; and of Ptolemaeus, some troops of Macedonian soldiers. 14 Ptolemaeus, who had no excuse for holding back for want of forces, supplied him with five thousand infantry, four thousand cavalry, and fifty elephants, but for not more than two years’ service. 15 In return for this favour, Pyrrhus, after marrying the daughter of Ptolemaeus, appointed him guardian of his kingdom in his absence; lest, on carrying the flower of his army into Italy, he should leave his dominions a prey to his enemies.
The relationship between Ptolemy II and Pyrrhus has been documented at more length by Adams 2008.
The numismatic evidence strengthens the claims of both Hammond and Adams AND suggests that it was far more than troops and elephants that Ptolemy II sent to Italy.
Update 4/6/2014: I was very happy to read this paragraph in Wolfgang Fischer-Bossert 2013 paper supporting a Pyrrhic dating for the eagle type at Taras on the silver.[Image links to full paper.]
Postscript 5 March 2014. If one is worrying about the use of the ‘Ptolemaic’ eagle in Italy, then this type of Larinum (c. 210-175, HN Italy 626) should also be thrown into the mix. Inspired by the Roman gold in all likelihood:
I’ve discussed coins of Larinum from this period before, here. And of course:
A. Burnett, The Beginnings of Roman Coinage, AIIN 36 (1989): 33-64, at 37 says:
Update 11 March 2014: Just a note to self. Consider also the coinage of Alba Fucens, Latin colony of 303 BC. HN Italy identifies three types, all silver obols (241, 243, and 244) that have Athena in a Corinthian helmet and an eagle on a thunderbolt, dating to c. 280-275. Crawford CMRR p. 47 sees the issue and those of Norba and Signia as likely struck to pay troops in the War against Pyrrhus.
The Stazio and Mertens’ literature is on order from ILL. The Italian Wikipedia has an article on the Monetaziono di Alba Fucens. There is an odd specimen in trade that I’d like to understand what’s going on with the mark behind the eagle better, looks like a fillet or maybe a striking artifact of some kind, image #1 and image #2. Also see HN Italy p. 11 and 180 for a little discussion of how the eagle and fulmen have been interpreted as symbols of Alexander the Molossian. I’d like to learn more about this coin type as well sometime. It’s a small bronze (Athena, Attic Helmet/close winged eagle and MOΛOΣΣΩN).
The scholar who seems to be most actively writing about Eagles on Coins in Italy is Carroccio. Most of his relevant papers are online with obvious titles, but the note the issue also comes up in his 2008 piece on Moneta Apula… also online on academia.edu.
