I don’t see it.
Get the high-res image and use a program that allows various zoom levels. You can see it faintly at a mid-level, and then at high zoom, you can see some of the ridges (that you don’t see elsewhere on the document).
Doesn’t mean it’s real...it could be a photoshopped certificate from someone else, for example, but I think that running that route is just going to lead to disappointment.
