Around a year ago I posted my first Eraviscan denarius, part of the hoard published by Rob Freeman in Essays Hersh. Around that same time I noticed that @arnoldoe had another from that same hoard on eBay and I quickly shot him an offer but, being the cheapskate I am, we couldn't come to an agreement on price. I recently decided to give it another shot and last week we finally came to an agreement and the coin arrived today, only 7 days later. Not bad for international shipping! This denarius imitates the types of Cn. Cornelius Lentulus minted as part of the Sertorian War effort circa 76-75 B.C.. The rudder has swapped sides and is engraved to the left of the globe, the wreathed sceptre has transformed and become more akin an ancient depiction of a lightning bolt, the reverse legend has been replaced with the tribe's name and most of the "EX SC" has been lost, though the "X" remains to the right of the lightning bolt. Even so, the basic design is easily recognizable. I personally particularly like this type and the others that use similar reverse dies because while multiple groups in Eastern Europe made silver imitations of Roman Republic denarii, the Eravisci were the only one to sign them so I was very happy to be able to add one of these inscribed types.

Being fascinated by imperial "barbarous imitations", I couldn't resist dallying with these republican "barbs". Besides, they lived between what's now Budapest and Esztergom, where I had a nice Donau-cruising holiday thirty years ago. Here are my Eravisci, both a different type from the OP. Danubian Celts, Eravisci. About 60-50 BC. AR denarius. Imitating C. Naevius Balbus and L. Papius. Diademed head of Venus right / IRAVSCI below, griffin running right. R.

Roscius Fabatus, issued in 64 BC. Obv. Head of Juno Sospita right in goatskin headdress, branch behind, C. before chin. Rev.

Silver coins of the Roman Republic from the first century BC were imitated in good silver in Dacia (north of the Danube, roughly in the region of modern Romania). The artwork is generally crude, although often attractive, and the obverse and reverse types of a single coin are often modeled on different official issues, as opposed to both sides imitating the same coin. Here is an ancient fourree combining two Republican types. I discuss it on its own page: http://augustuscoins.com/ed/imit/RRimitation.html
