ID Help Please. Alexander Tetradrachm?

I got the answer from a group I am in on the book of face lol. I don't think it's cast but it's easier to tell when it's in hand. Anyhow, it can go in a flip now and get tucked away.

The vast majority of Alexander's coins had mintmarks or monograms so they can be identified. A few have no symbols at all. The main reference for Alexander coinage is by Martin Price, Coinage in the name of Alexander the Great, two volumes. If you live near a major library they may have a copy but searching for the few examples without any markings would take some time.

You could take it to a coin store that has an XRF and test it. You'd at least know if it's silver or not, if not then you know for sure it's a fake. There are a few dealers that will examine a coin for authenticity for a fee. I've sent a few to David R Sear but I don't know if he currently still does this. NGC grades ancient coins if you want to go that route.

By the way I talked to a dealer who said dating his coinage by whether Zeus' legs are crossed is a general guideline but there are exceptions.

Yes, there are "unofficial" or "barbaric" imitation coins tribes/people made to look like coins of other cultures. They are not modern fakes, were made in ancient times. Your's may be one of these. Usually the style of the design is not correct but I don't know much about them.

I have an ancient counterfeit Athens new style tetradrachm, bronze/copper inside, silver plated outside. These are called fourree.

That's quite a nice looking coin even if it's a Fourree.
