Seems like a good excuse to post one I haven't been able to ID. Looks Antoninus-Piusy to me, with something altary on the reverse. But I can't find one like it anywhere.
Don't compare the coin to al coins when it seems so obviously a bronze of Antioch using the type use by most emperors for the first 250 years or so. This is Augustus: Tiberius: (Images from old CNG sales) Not all dies will have the exact same portrait (Tiberius may have a smaller nose so you can't just say this one must be that one based on two photos). Feel free to study a hundred online images and make a guess but certain ID would be easier with slightly better coins.
I've never been so grateful for not having made a typo! (Reminds me of the CBC interviewer cursed with the President of the BC Fallers' and Buckers' Association as his guest. Allegedly he was highly aware of the potential pitfall, and practiced thoroughly before going on air. The practice didn't help... )
My apologies for yet another Crocodile coin quite worn and with scratches. After reading the very interesting links provided by dougsmit http://www.forumancientcoins.com/dougsmith/impossible.html, Cucumbor and Julius Germanicus http://www.asdenimes.com/ and http://as-de-nimes.pagesperso-orange.fr/classification/classification.html I wonder ( my French is very basic....) which one is the most likely class of my coin. Augustus head is bare so it is not a class 3 or 4. The hair of Augustus and Agrippa seems to be pointed, feature also to be found on some smaller early class 2 coins, so my guess would be class 2 therefore RIC 155-157. Is this correct? Diameter 24 x 25 mm (seems to be too small for a class 1), weight 13.89 g Obverse: IMP / DIVI·F Heads of Agrippa (left) and Augustus (right) back to back Reverse: COL·NEM Crocodile chained to palm with tip right; above on left a wreath with long ties Chris
