Leo Posted July 10, 2022 · Member Share Posted July 10, 2022 Who doesnt like a nice silvered Antoninianus or Follis? In this new video, I explore a bit of the most recent theories on how the roman mints achieved this silvering effect. Post your silvered coins, and remember to leave a like and a comment to help youtube push the video! 🙂 We've just hit 10.000 subscribers, thank you very much for the continuous support!   19 1 Quote Link to comment Share on other sites More sharing options...

Curtisimo Posted July 11, 2022 · Supporter Share Posted July 11, 2022 Another fun video @Leo! Of all my silvered coins I think this one probably maintains the most silvering. Roman Empire Diocletian, AD 284-305 AE Follis, Ticinum mint, struck AD 296-297 Dia.: 31 mm Wt.: 8.63 g Obv.: IMP C DIOCLETIANVS P F AVG. Laureate head of Diocletian right Rev.: GENIO POPVLI ROMANI.

kapphnwn Posted July 11, 2022 · Supporter Share Posted July 11, 2022 Definitely one of the no or very minute silvering remaining coins Nurmerian Ae Aurelianus Lugdunum 283-284 AD Obv Bust left radiate draped and cuirassed holdin spear over shoulder and carrying shield Rv Pax standing left holding olive branch and scepter. RIC 395 2.79 grms 22 mm Photo by W. Hansen I have always wondered how some coins have almost intact silvering whereas others like this one have virtually none left. I do not see this coin having much circulation so I am left with the thought that the modern cleaning process may have inadvertently stripped the silver from the coin or in this case turned it black. The other option is that some of the coins missed the silvering process all together. 12 Quote Link to comment Share on other sites More sharing options...

Sulla80 Posted July 11, 2022 · Supporter Share Posted July 11, 2022 (edited) An informative video @Leo, thanks for posting! I think there are a couple of additional factors that have coins looking the way they do in hand today (in addition to @kapphnwn's comment about cleaning): - oxidized silver (from sitting in the ground for a long time) which can be black and not silver which makes the presence or absence of silver harder to see without cleaning and risking damage to the coin e.g. this coin - additional leaching of metals from the surface layer as the coins sit, buried over centuries - changes the composition of the surface - I think this can work both ways - enriching and depleting the silver layer Here's a nice graph from G. C. Haines 1941 illustrating data from J. Hammer (1908) on the decline in silver content over time - more recent studies and techniques for analyzing the silver content may have improved on this view in details, but this is roughly correct. I will add a silvered Probus with high copper content from Lugdunum, January-August 282 and here's a Gallienus which at least gives an illusion of being much finer silver from Colonia Agrippinensis (Cologne) which supplied coinage for troops stationed on the frontier Gallienus, AD 253-268, AR Antoninianus, Colonia Agrippinensis (Cologne) mint, 1st emission, AD 257-258 (Joint Reign)Obv: Radiate and cuirassed bust rightRev: IOVI VICTORI, Jupiter, holding Victory and scepter, standing facing, head left, on cippus (small low pillar) inscribed IMP/C E S in two lines (IMPerator Cum Exercitu Suo)Ref: RIC V 21 Edited July 11, 2022 by Sulla80 13 Quote Link to comment Share on other sites More sharing options...

I'm sure it is roughly correct, but seems a bit odd in a couple of regards: 1) Why is the silver content shown so low after Aurelian's reform? Weren't the XX:I radiates closer to 5% silver (graph makes it look more like 1%) ? 2) The debased-silver successor to the radiates was surely the debased-silver nummus. The 95% silver argenteus seems irrelevant. It'd be a bit like the US mint saying they've switched back to the gold standard since they issue some gold coins.

Octavius Posted July 12, 2022 · Supporter Share Posted July 12, 2022  Several silvered 3rd century Antoniniani...  1. nicely silvered Valerian some remnants of silvering are still retained in this Ant. of Tacitus (mostly reverse and in devices). a little more silvering in this one of Tacitus... a nice , fully silvered Diocletian - this one probably never got to circulate much at all... silvered Probus Adventus Ant....  Gallienus... and another Gallienus/Virtus with full silvering. 5 1 Quote Link to comment Share on other sites More sharing options...
