Those pics are much better. The RR bronze looks authentic to me - style and fabric look good, the diameter is correct. This denomination is called an "as." I concur with Bing. The rest of the coins are likely worthless. The RR bronze is the jewel of the lot - since you asked about market value, at least $50, possibly more to someone who specializes in them. More importantly, it's an interesting part of ancient Roman history, and the history of coinage in general. These coins were minted around 211 BC and later, so you've got a piece of two-thousand-year-old currency in your hand. If you only paid $15, congratulations are in order for the Janus/Prow RR.
I added more pictures in my dropbox, i took alot of the edges cause i was concerned about them, could u please take a look ? https://www.dropbox.com/sh/g4fjei3qhv3edrv/AAB05riO4X5Cop0k1X0WpYNea?dl=0
John I dont want to get my hopes up just yet, would you be kind enough to review a couple of new pictures i uploaded to dropbox of the edges of the coin https://www.dropbox.com/sh/g4fjei3qhv3edrv/AAB05riO4X5Cop0k1X0WpYNea?dl=0
A beveled edge is normal for Roman Republic bronzes. They used a lathe machine to trim the flans before they were struck. Sometimes beginners confuse this with the casting seams you find on forgeries, but that is not what you have. Here is a similar coin of mine from the same period...
Thank you so much john. so the justianian coin is fake and the RR bronze is real. But what are the other coins ? the lady with the veil ? what about the one with the cross in the back on what looks like pillars ? it looks like a bell to me but im not sure, it must be from the byzantine period. Also does anyone have links to the coins i have, possible on numista or some kind of catalog ? ill even take ebay listing as reference
I have no clue about the veiled lady. The other is, I believe, a Roman provincial coin of Philip II with tetrastyle temple on reverse, but it's too worn for me to narrow it down, and I'm not even certain it's Philip II (that's Philip II the Roman emperor, not the father of Alexander the Great).
The one that has the pillars is a 3rd century AD Roman provincial struck in Antioch in Seleucis and Pieria. Hard to say which emperor without trying to decipher the very faint legend on the obverse, but likely to be Philip I, Trajan Decius or Trebonianus Gallus. Here's one is slightly better condition:
You'll find a thorough listing of Anonymous RR bronzes on this page. There are quite a few varieties in the Janus series, but I don't know them well enough to attribute yours.
Sorry, I meant Philip I, as Zumbly says. Seleucis and Piera is a good guess! But other provinces used tetrastyle temples as well.
It's true other provincial cities had similar reverses but I believe I see the distinctive Tyche of Antioch within the temple.
I can't read the legend of the obverse on your coin from the picture, and perhaps it's too worn in any case, but the portrait does look closest to Trebonianus Gallus to me and his issues do seem to be the most common too. Can't say for certain, unfortunately.
