Not that I've heard. To look authentic, these have to be hammered, by hand. The Chinese specialise in mass-produced, machine-struck fakes.
Hand-struck fake coins (ancient and mediaeval) aimed at collectors tend to come from Eastern Europe, notably Bulgaria. But their products usually look better than these.
I'm no expert in late Byzantine, and I don't know enough about the series to be able to identify the emperor just by the pictures. Sorry.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
