Post A Photo Of Your Ancient Roman Commemorative

Spent an hour trying to ID these as the seller didn't. My guess on the first one is;
Urbs Roma commemorative, Struck 332-333 AD, VF , 2.01 g, 17.2 x 18.3 mm. Minted in Lugdunum (Lyons, France). Urbs Roma Commemorative AE3. . VRBS ROMA, visored, crested helmeted bust of Roma left in imperial cloak / she-wolf suckling Romulus & Remus, two stars above, star PLG in ex. Lyons RIC VII 267

I'm thinking the second one is
Constantinopolis commemorative AE 3, Struck 330-331 AD, VF , 2.29 g, 16.2 x 17.0 mm., minted in Trier, Germany. OBV.: Constantinopolis left, CONSTANTINOPOLIS. REV.: VIctory left on prow. Constantinopolis Commemmorative AE3/4. Time of Constantine the Great. CONSTANTINOPOLIS, laureate, helmeted & mantled bust left holding scepter / Victory standing left on foot of prow with scepter and leaning on sheild. CONSTAN-TINOPOLIS, laureate and helmeted bust of Constantinopolis left, wearing imperial mantle, holding reversed spear / No legend, Victory standing facing on prow, head left, holding sceptre and resting left hand on shield. Wreath in left field. Mintmark TRP dot? (unlisted mintmark for this issue). RIC VII Trier 554 var

Thanks Martin, I agree with you on the 554. I don't see the dot either but looking at Wildwinds the example of 554 showed TRS instead of TRP.
The other coin could be a dot and I won't know for sure until it arrives and I can look at it closer. The seller's photo made me think it was a small star because it did not look round.

Here is another resource you can use. Not sure if you know about it or not.

Check out the RIC Lists, Excel Spreadsheets.

Those Excel spreadsheets are extremely useful for attributing a lot of late Roman coins and some others as well.

For late Romans and 3rd century radiates I pretty much just rely on the Helveticas spreadsheet. More precise. For earlier stuff I use WW.
