All the coins have different reverses. The emperors in the lot are:
1) Philippus I, diameter: 26mm, weight: 17g, rev: Lion & Bull
2) Gallienus, rev: SALVS AVG
3) Aurelianus, rev: ORIENS AVG
4) Constantius II, rev: GLORIA EXERCITUS
5) Valentinianus I, rev: SECVRITAS REI PVBLICAE
6) Constans, rev: VICTORIAE DD AVGGQ NN
7) Licinius I, rev: IOVI CONSERVATORI
The 8th coin is a commemorative marking the foundation of Constantinople. The female figure on the obverse is the personification of Constantinople while the reverse is victory on a prow and alludes to the naval victory of Crispus followed by the capture of Byzantium.













These photos are the best I could do with my phone, as with all ancient coins they're better in hand than on the photo. The coins can probably be further cleaned to make them shiny but in my opinion it's unnecessary.
Asking price is 40$ (registered shipping included in the price) payable by paypal. Since shipping is included in the price that comes to around 4$ per coin. Considering the lot is all different emperors with different reverses and it has a large 26mm coin in it I think the price is fair.
I can also consider a swap for one or two coins of similar value.
If anyone is interested please let me know.
