I personally would start smelling a rat!
What’s the alignment between the reverse and observe of the two coins, do we know?
In the bottom right of the video, where the metal appears to stretch out, like it’s been struck slightly more heavily at that point, I’d expect to see some differences in the height/movement of the devices between the two coins on account of that. Also the beading is so perfectly matched for both coins, though in the bottom left of the video it appears as though the beading has been chopped, maybe filed?
