Welcome @wajobrer. You will get a better response if you post this coin in it's own thread. Easy to do. I doubt the coin is authentic, but I'm not certain. Where did you get it from and, if it's not too intrusive, how much did you pay?
I bought one of these Tiberius issues two months ago. Not as nice as those posted by Eng and Drusus, but one that shows decent detail. Its off-center strike is probably why it was in my price range. Part of me wishes I had waited a bit and ponied up an extra $50-75 for a better quality version. I guess it's always a tradeoff between quality coins vs. quantity. I'm trying to discipline myself to prefer the former.
Nice Tiberius @Eng ! Well done. I have ALSO heard that this Augustus COULD be a Tribute Penny too...
