Incredible find! I dont think I have ever seen a provincial Mariniana before! Please do post pictures after cleaning.
Way COOL, @galba68 ! Super find. I only have the Rome version: RI Mariniana AR Ant 253-254 CE DIVA Crescent - On Peacock flying 21.2mm 3.1g RIC VII 6 Rome
Wow! I've never seen a coin of Viminacium with Mariniana. This is my only coin from that city with an empress on it -- from year XI: Herennia Etruscilla, AD 249-253. Roman provincial Æ, 12.67 g, 27.45 mm, 7 h. Moesia Superior, Viminacium, AD 249-250. Obv: HER ETRVSCILLA AVG, diademed and draped bust, right. Rev: P M S COL VIM, Moesia standing left between bull and lion; ANXI (year 11 = 249/50) in exergue. Refs: SGI 4220 var.; BMC 3.18, 32 var.; Pick 136; Moushmov 48.
Clean it carefully. It looks like a keeper. Billon can be ruined easily. David Sear says in SGI that this is the only Provincial coin issued in her name. However we might note that her 'Imperial' antoniniani are attributed to the Viminacium mint as well.
Great coin and presumably a rarity. I also have a Herennia Etruscilla...it's about the size and weight of a sestertius, so I guess therefore that it had similar purchasing power.
WOW. I mean, all your finds are "wow", but this is a wow among wows. Wonder when you're going to turn over a chunk of sod and see a Pertinax aureus lying there, twinkling in the sun...
My Mariniana coin -- an antoninianus -- was minted in Viminacium as well: Diva Mariniana, Silvered Billon Antoninianus. 254-258 AD, Viminacium Mint. Obv. DIVAE MARINIANAE, Veiled and draped bust right on crescent/ Rev. CONSECRATIO, Peacock standing, head right, tail in splendor. RSC IV 4, RIC V-1 4, Sear RCV III 10068. 21.5 mm., 3.9 g.
I may have to walk back my statement that my coin was minted in Viminacium, which was in the seller's description, and is how Wildwinds describes it: Sear suggests that this type was minted in Rome, even though the mintmark "V" sometimes appears on the reverse in the right field. Which it doesn't here. Or on the coin shown in Wildwinds, for that matter.
