Quinarius of Diocletian.

[Genio popvli romani]

Here is a quinarius of Diocletian that just sold for €225.
I would say the bust seems to come from Rome but the obverse legend is IMP C DIOCLETIANVS AVG and the reverse is only listed for Siscia and Lyon (Bastien #7).
May be, it is in King but unfortunately I don't have it.
1.88g

It's a nice example, it's RIC Vii Siscia 283. Also in King, Siscia 2.

Don't you think the bust can also be draped (fibula and part of paludamentum on right shoulder) like the attached coins from Trier mint ?

[Victor]

that's a good question. for early Imperial coinage, there is a bust type with "slight drapery" over shoulder; so maybe LRB's should also have cuirassed with slight drapery over shoulder, or slight cloak over right shoulder.

[Genio popvli romani]

It is what Bastien called naked bust with small fold of paludamentum on left shoulder (O2,O3,O*2,O*3) but he also described the B busts (B,B1,B*,B*1) as radiate/laureate with cuirass or cuirass and little fold of paludamentum like the attached one.
In fact, I assume that the previous busts I have attached have the cloak weared like a cape.
Is the King specimen illustrated ?

[Victor]

actually it is

2a does show a bit of cloak over the shoulder versus 1a which shows none.

2a looks like a die match with the example that just sold.

[Genio popvli romani]

Die link indeed ! So, not unlisted !
But did she make a difference between 1a and 2a ?

[Victor]

I just noticed that 1a is a gold coin, but she calls both "laur. cuir. r."

2a is the same coin as RIC 283, it is first recorded by Alfodi in Numismatic Chronicle (1929) p 282- 3  #11.

Thank you.
So, laureate, cuirassed, right.
