Coins of Alexander the Great

Can't vouch for the dealer but the coins he shows all look legit.  The prices are crazy, but they are all take offers so it is expected.

Good video on the coins of Alexander the Great.

Check out his youtube channel and his eBay store.

Again, I don't know the guy at all, but he produced a solid informative video.  

Maybe he is worth getting to know, you know.
