I got an email about an upcoming auction and immediately noticed the fake Julian II from Cyzicus. I emailed the seller and they pulled the coin.
The first coin below is an older example of the fake, the second is the recent example, notice that they have both been chemically "aged"
Here is an additional topic with many more examples of this fake.
