[QUOTE="Aestimare, post: 3658614, member: 98537"]Hi Roerbakmix, I don’t have the right answer to your enigmatic coin, but I have some ideas. The shape, weight, surface appearance could indicate a well known strike/lost wax casting method used in Gaul in the roman denarius area. But not good silver ones (c.a. 1,80g-1,90g), fourree coins (c.a. 1,30g-1,40g), on an “unstroked” copper blank wrapped with wax before the strike (the manipulations of the blank after the strike on the wax explain the flattened shape and unstroked areas). Clay powder mixed to ashes will prevent the grip with the refractory past. Once cooked, at about 400°C the refractory moulds are immersed in water to avoid black oxides at the surface of the coins. (Katherine Gruel, Laurent Popovitch. Les monnaies gauloises et romaines de l'oppidum de Bibracte. Glux-en-Glenne : Bibracte, Centre archéologique européen, pp.28-31, 2007, Bibracte (Glux-en-Glenne) ISSN 1281-430X; 13, Vincent Guichard, 978-2-909668-16-1. [URL='https://hal.archives-ouvertes.fr/hal-00172334']⟨hal-00172334⟩[/URL] ). The problem is : the following coin [ATTACH=full]983462[/ATTACH] (seen on eBay 2012-12-05), technically and geographically maybe comparable to yours, show an obverse and a reverse that don’t match. Obverse and reverse are both from the Aedui tribe, but are not dated of the same period. Another coin combines a DVBNOCOV/VIIPOTAL (same observation : same Aedui tribe, not the same period). Another one combine obverse and reverse from 2 different close tribes : [URL]https://www.acsearch.info/search.html?id=179663[/URL]. The problem is then, that you possibly have to look for 2 different coins. The reverse could be an Aedui DT 3188 (just select DT 3188 on Acsearch), but the obverse ? Aedui, Sequani, Lingones, Leuci, Helvetii ? Good luck Roerbakmix ![/QUOTE]
