Needless to say, the anepigraphic version of this coin is pretty rare and was presumably a special issue, somehow connected with the founding of Constantinople. Some oohs and ahs, please, as I’m sure my family won’t really appreciate it! 😆

I hope you will forgive a trip in a kind of way-back machine, but a few weeks ago in this thread you showed us your anepigraphic "eyes to heaven Dafne piece, which was impressive at first blush.  The type is discussed by Speck and Huston in their study from 1992, without illustration, but in their table 3, second issue, they note that of the few examples known at that time all but one example are from officina A.  The one that got away is an R5 from officina S.  Is that your coin, or have more of these come to the surfance since 1992?  How much has changed since 1992?

Some of you have some really excellent coins of Leo, at least by my standards.  MC9: That lion reverse is tops in my book (probably since I don't have one).  And Qcumbor surprised me with an AE2 - didn't expect to see one.  My examples are more modest, but such as they are, here they are:

LEO

Leo I  AE4 11mm  Constantinople  RIC X 714
DN L -  E  O  diademed and draped bust r.
No Legend  Verina stg facing, holds globus cruciger (in r), and (crosswise) scepter
left field: b     right field: E

Leo I  AE4       9x12mm        RIC X 694

Latin monogram w/ (S) above

Leo I   AE4    10x11mm      Constantinople?      RIC X 702
DN L - E O   diademed draped and cuirassed bust r.
No legend. Emperor stg facing, head to L; holds long cross and places hand on kneeling captive.
Left field: type A (clear)      In exergue: CO

This next has the same reverse motif but it has a different texture

Leo I    AE4    10mm      Constantinople?      RIC X 703
DN L - _E O_   diademed, draped (and cuirassed?) bust r.
No legend. Emperor stg facing, head to L; holds long cross and places hand on kneeling captive.
Left field: Cross?    

VERINA

Coins were issued in the name of Verina that bear her legend.  In lieu of one of those I will show another example of her reverse on a coin of Leo with clear details:

Leo I       AE4       11mm        Constantinople       RIC X 714
DN L -  ___ ;   diademed and draped bust r.
No Legend.  Verina stg facing, holds globus cruciger (in r), and scepter (crosswise)
left field: b     right field: (E)

I have been reluctant to show my latest since they are so poor I have not been able to attribute them to city. But then again, they do have some form, so here goes.

For Theodosius II

For the Valentinianus coin I stand by what I have written.

 I have inquired about this in the past ( started more then 20 years ago ) on various coin forums and it was suggested that given the weight, diameter, thickness and ( material type ( that is why i have it tested )) of the coin, it should  be called a half siliqua in the absence of an existing name given its weight  .

Thank you for the reply.  I am beginning to get the picture, I think.  The crux of the whole matter is your earlier experience with the Valentinian piece, which you have carefully examined, and discussed with collectors, but apparently have not formally "presented to the world" as a new discovery.  May I encourage you to do that, since the verifiable discovery of an unknown denomination is no small thing. That having been said, it is also a fact that our standard reference for this material is hopelessly out of date and can be expected to have many gaps.  Might I suggest a report to the ANS (if in the US), or whatever numismatic agency operates in your part of the world, might be in order so your piece may have referential value for other students of this material?  If it is to be authoritative, it needs to be properly vetted and published. From what you have said here it sounds as if you have seen something worthy of a closer look. I would look forward to hearing more about that coin.

Thanks for sharing it.  All the best.

@Severus Alexander:

You are right, looking through a microscope to the crack, the coin is an AE4 (copper/bronze )core.

Great eye !

( I corrected the text ).

@Irbguy :

in this regard : this is the explanation in RIC IX on page XXIX:

the bronze underwent many changes, and its relation to the gold and silver in any of its transforations is still a matter of conjecture. it is generaly accepted that the bronze throughout our periode was supposed to contain a slight alloy of silver, with would materially increase its value above that of the normal ratio of unalloyed bronze to gold and silver

( this coin was tested by a silver smidt, there is a slight alloy of silver present on the outside ).

 

 

I gut tells me this should be examined privately, but the errors have not been corrected.  So, new to the list as I am, I will raise the question. Our interest is only to set the record straight, and maybe to help a fellow collector who is trying to make sense out of a confusing phenomenon.

With all due respect, MC9, you have identified the coin as a half siliqua, claiming it to be silver.  Citing Pearce on the question of silver as an adulterant in a bronze matrix misses the point.  The coin which corresponds to RIC IX 26c is listed by Pearce as an "Aes IV" directly under the word "BRONZE."  Pierce's comment on page XXIX applies to all bronze coins of this period.  But you have singled out a few that you call "silver" (cf. also your first entry of May 10 for Valentinian, which you also identify as a half-siliqua, unlisted). You do not make this distinction for all late bronze coins, but you did for these two, originally noting in both cases that RIC missed it.  What tells you these are silver coins when the others like them are not?

I hope I'm not too late to the party.  Hunted for a missing coin and finally had to give up.  So I can only show two of the coins for May 20. 

One request: In comparing this material with the descriptions and illustrations in RIC X various points of difference were noted such that the catalog description and photos do not always agree or line up.  Please check my attributions against your own interpretation of the listings in RIC X and as needed comment on what listing might be a better fit for each coin in question.

Galla Placidia

I had no luck in finding the Galla Placidia I had acquired a few years ago. By way of recompense let me show a couple of better examples of Edoxia AE3s I came across and would have used earlier.

That's for an AE4, of course.  @mc9 suspects his coin is actually silver, though. (It looks AE to me in the photo, though.)

Since bronze is (and long has been) an alloy of copper and tin, sometimes with a bit of zinc thrown in, it is not hard to queer the mix and get a slightly silvery look to it. 

After seeing the "three emperors" GLORIA ROMANORVM type for Honorius shown by mc9 above, I decided to go ahead and show a wrecked up example of the same type for Arcadius, which I had not realized existed for him.  It too shows the star on obverse to the left of the head.  

Arcadius AE4 - 13x14mm Alexandria mint; 383-408
DN ARCADI - VS PF AVG  diademed, draped and cuirassed bust right; star behind head
GLORI - A ROMANANORVM    Three emperors standing, two face front, middle facing r.

Now on to the emperors of the day, of which I am only able to show one:

HONORIUS

I will show one example in the AE2 module, two in the AE3 module, and two in the AE4 module:

Honorius AE2 - 21x23mm    Antioch mint; 383-408
DN HONORIVS PF AVG  rosette diademed, draped and cuirassed facing r.
GLORIA RO - MANORVM ; emperor standing with labarum (L) and orb (R)

Honorius AE3 - 18x19mm  Cyzicus mint; 383-408
DN HONORI - VS PF AVG   pearl diademed, draped and cuirassed bust right
VIRTVS - EXERCITI   emperor standing (left) w/ labarum (L) and shield (R); Victory placing wreath           In exergue: SMKB

Honorius AE3 - 17x18mm   Cyzicus mint; 383-408

SALVS REI - PVBLICAE; Victory bearing trophy in r hand/shoulder leads captive to L
Left field: dot   In exergue: SMN[] (A or delta)

The large ball at top right, just before the "P" of PVBLICAE, appears to be the top of the trophy.  The function of the dot in left field is uncertain.

Honorius AE4 - 13mm    Antioch mint; 393-395

Are you sure this coin is silver, @mc9? Could it just appear so due to some unusual patination? (The flan crack at 9 o’clock on the rev. will be useful for checking this.)

The attribution is actually RIC IX 26c for Cyzicus.

It is indeed Antioch

Q

Thanks for the reply, and sorry for the ambiguity. The question mark was for the officina, not for the mint. My notation must have been a bit too cryptic.  I'll have to figure out another way to signal when I can't find/read an officina mark. 

RIC does not list this type for an AE3, but does for an AE2 and for a small module AE4.  It does note a larger module AE4 at 14-16mm, but not for this reverse type for Eudoxia.  Since I did not give the measurement (15.48mm), the whole thing was out to sea.  If I were to call it a small AE2, then the officina would be "Beta" but if it were the small mod AE4 the officina would be "Epsilon."  This one falls through the cracks, but then again, RIC IX came out in 1933, and I don't know the latest wisdom on this one.  Does anybody know?

And here are a few varieties for Arcadius (and one more for his wife).

But my Arcadius bronze with the T that you identified as a Tau cross was, in fact, minted in Alexandria.

Ah!  Actually, that's good.  I hate it when a trend is too localized.  I'm glad to be wrong about Alexandria in this case.  I also noticed that Antioch also used the Latin cross on their mint product, apparently more often than not.  So it swings both ways. 

Be all that as it may, I think we are safe in attributing the use of such a symbol to a Greek influence.  Whether we find that in the preferences and policies of the mints or those above them or some other source remains to be sorted out.

1 hour ago, DonnaML said:

the reverse of my Valentinian I solidus posted above, minted in Antioch, shows the Emperor holding what is likely a vexillum with a Tau cross

While there is no direct familial lineage from Arcadius to Valentinian (since Theodosius was a General and the son of a General who had served under Valentinian) from the standpoint of this distinctive style of cross there is a strong point of connection via the mint at Antioch.  All of the coins we have been looking at so far which bear the Tau cross came from that mint, whilst the neighboring mints, such as Alexandria, tended to use the Latin cross.  I find that a bit odd, since it is throughout the west that we find the highest concentration of Greek speakers in the late empire, and that is the heritage which continues beyond the end of empire into the so-called Byzantine period. 

1 hour ago, DonnaML said:

That "T" can't be a form of cross, because some coins of the period have both a T and a cross in the reverse fields. And it doesn't have anything to do with the mint or the officina number, because it appears on coins of various mints and various officinae within those mints. Perhaps somebody here knows what it means.

Not sure why you say it "can't be a form of cross."  The Tau cross was an ancient form that was used for the crucifixion of St. Antony.   Since T was the symbol for numeral 300 some of the Ante-Nicene church fathers associate the figure with the cross of Christ (as alternative to Latin cross.  When I get to it I will be showing a coin with both the Latin cross and Greek "tau" cross, which I suspect was intended to show respect to both of the main Christian faith traditions of a divided empire.

Edit: Come to think of it I showed one of each in my selections for Ael. Flacilla.  A Latin cross from Constantinople, and a Tau cross from Antioch.

There are some very nice coins of Valentinian II being shown here.  Most impressive.
Before presenting my coins let me correct an error in my last post: I should have said that res is a fifth declension noun, not 3rd. FWIW.

I have selected four coins for Valentinian II; 3 Ae3, and an AE4, which I think do not duplicate what others have posted so far.

Nice bronze Sev Alex, something not in RIC VII.  I have always like the Dafne reverse, and the fact that it gets tangled up with the campgate reverses.

9 hours ago, Severus Alexander said:

I see some dealers parse the legend as Rei Public(ae), i.e. literally “public things,”

Actually, parsing REIPVB (or reipublicae) as rei + publicae cannot yield "public things" inasmuch as rei is a feminine singular form from the third declension noun "res."  It is either genitive or dative singular.  Publicae is the associated adjective parsed as a first declension singular to match, which in its unabbreviated form "reipublicae" appears on a solidus of Valens.  The word which disambiguates the grammatical case of reipublicae, is the noun "reparatio" a third declension singular which by virtue of prior position forces reipublicae to take the genitive: the restoration of (the) public order/affair/matter.  Contrary to my earlier comment, this is not a throwback reference to the Roman republic, but rather, I think,  speaks of civil order despite the growing separation of east and west.

In this rendering, the figure being elevated by the imperial recognition is the public order, and is feminine by virtue of the grammar of the expression.

13 hours ago, DonnaML said:

Or maybe she's supposed to be Roma after all. See the book @John Conduitt linked, "The Idea of Rome in Late Antiquity," at p. 28:

Well, think about it.  While both Roma and Republica are feminine nouns, If the kneeling figure which is being elevated by the attention of the emperor (large central figure) were Roma, wouldn't the coin inscription have mentioned that? (reparatio romae?) Why does it hearken back to Republica?  For many in the east "Roma" was tied to a city; a city they sought to keep at a distance since the time of Diocletian.

A bit above Donna asked: "So: Who is that woman?" after noting, " Could she have been intended as a personification of “the Republic” itself? "

Based on the associated text I think you have put your finger on it with that query.  The figure in question is to be associated with the "REPARATIO REIBVB(LICAE)," i.e. "Restoration of the Republic." Note that the abbreviated word "REIPVB" is a first declension genitive in Latin (republicae).  If we understand the large central figure to be the Imperial personage dujour (Valens or Gratian or whoever), then his gesture is one of elevating the status of the kneeling figure.  The inscription is being given a hyper-literal rendering based upon the grammatical gender of Latin first declension nouns.

 The principal claimant to this treatment of this epithet on coinage (per Stevenson "Dictionary") was Valens, but insofar as his coinage coincided, Gratian must have been a co-claimant to the distinction de jure as part of the Imperial majesty.  It was all in a spirit of lighthearted Latin fun.

Six items in sets of two of decreasing size from AE2 to AE4. These range over the whole length of his reign.
