I did not find pure proof but I found things that will let you think.
See last 2 hits. 2 different coins with the same piece of whitepaper. This whitepaper piece should be unique cuz every coin has his own feautures. And the same example is too obvious.
Now I did not exactly find which one was first, but I found this:
may 2017
june 2017
I know, this isnt a good proof but it gave me some doubts.
1 of these is fake anyway!

There isn't too much to be seen from this, you could be right but this doesn't really prove anything. It's suggestive at best. Still as with anything it would be nice if this could be cleared up just to remove any doubt.
