This is my 3rd Col Nems Chained Crocodile type with Augustus and his #1 general Marcus Agrippa BFF: Nemausus Augustus Agrippa Crocodile 10,71 G/26 mm I bought it primarily due to the countermark in front of/on Agrippa's nose! It may be "DD", Decreto Decurionum (The Decree). Though, it doesn't look entirely like the standard DD. Here are my DDs below (hopefully you wont be disappointed): Augustus Hispania, Julia Traducta. 27 B.C.-A.D. 14 Æ 25 (24.9 mm, 10.27 g, 4 h). PERM CAES AVG, bare head left / IVLIA TRAD, in two lines within wreath. Countermarked “DD” (Decreto Decurionum) RPC 108; SNG Copenhagen 459. It looks more to me to be the much more rare "PP", Pater Patriae (Father of the country). I have no examples of the "PP" to share. Here is a pic from my phone which kind of makes it look like the double Ds, but for the fact that the countermarks circle is much larger than just the DD, you can sort of see a P's tail on left and then a curious H or T below the second P/D on the right: In hopes of getting a better look at the lower half of the countermark I broke out a contraption that my Dad got me a while ago for an extreme close up: (No. Not that kind of extreme close-up) (I meant to share a picture of this contraption in Doug's thread but had it packed away...until I needed it this afternoon) This kind: I can't make heads nor croc tails of it. But I am still really geeked to have it. If you are interested in learning more about the coin type, I can think of doing you no better favor than sharing our own @dougsmit 's web page on these: http://www.forumancientcoins.com/dougsmith/impossible.html (Hopefully Doug is cool with me sharing his handy work and doesn't want to countermark me in the nose!) Speaking of these types, here are my other 2 (OK, 1 and a half): Augustus with Agrippa Roman Provincial Gaul, Nemausus. 27 BCE-CE 14 Æ dupondius CE 10-14. IMP DIVI F, P-P, back to back heads of Augustus and Agrippa / COL NEM, crocodile chained to palm branch, wreath above . RPC 525; RIC 160. aVF. Augustus (27 BC-AD 14), with Marcus Agrippa (died 12 BC). Æ halved dupondius (26mm, 7.10 gm). Gaul, Nemausus, AD 10-14. IMP DIVI F P - P, adduced head of Agrippa wearing rostral crown / COL - NEM, crocodile chained to palm tree, two further palm branches below crocodile. RPC 525. RIC 159. A outstanding portrait. The left-facing bust on this attractive issue of Nemausus (modern Nimes) depicts Marcus Vipsanius Agrippa, perhaps history's greatest sidekick. He was born in 63 BC, the same year as Gaius Octavius, with whom he struck up a close friendship in adolescence. Octavius recognized Agrippa's remarkable qualities as a soldier and statesman and relied heavily on him to put his various plans into action. Agrippa's mastery of strategy secured the naval victory over Sextus Pompey at Naulochus in 36 BC, and the defeat of Mark Antony and Cleopatra at Actium five years later. After Octavian assumed the title of Augustus in 27 BC, Agrippa was clearly regarded as second-in-command and the likely heir to the throne. His many building projects, financed out of his own purse, helped transform Rome from a city of brick to one of marble, and his commemorative inscriptions survive on many important monuments, including the Pantheon. His name continued to be revered long after his death. coin, struck two decades later, attests I would love to hear any theories or thoughts on my new coins countermark, see all of your types of this EXTREMELY popular coin, curious countermarks or anything else that makes one learn or laugh!
