I disagree with you, but cannot be bothered arguing anymore.
It matters little anyway. See it as you wish to, and I will do the same.
Edit:
Actually, I have decided to expand on my thinking on this so you can better understand my position.
Let's step this through. Imagine you have one unintentional scratch on a coin. Is it still a genuine coin? Yes, of course. But what if that exact same scratch is intentional? Is it still genuine? Yes, but we call it graffiti. Now, what if there are hundreds of unintentional scratches? Is the coin still genuine? Yes, but we'd give it an F grade or worse. What if those exact same hundreds of scratches are intentional? Does that make a difference? Exact same damage on the coin, but with a different intent. You'd say it probably doesn't make a difference to whether the coin is genuine, right? But we've just changed thr majority of the surface of the coin, with intent.
And then we get to intentional smoothing. Why is that different to intentional scratches? Because now the intent is to improve the look of the coin. Is the coin still genuine? It was intentional. Most would still say yes.
But then we intentionally carve into the coin, improve designs etc.... say around 20% of the surface. Is it still genuine then? I believe most would still say yes, but it is tooled.
But then we change 50% of the surface? What then? Is this suddenly where we draw the line, and say it's a fake?
Or at 51%? Or 49%? Or do we have to go up to 90%? What percentage of the original surface is required for it to still be genuine? And why is this different to intentional scratches that also changed the majority of the surface?
Because the aim was to improve the surface? Ridiculous thinking. It's all subjective.
Or do you have to make it look like a different coin for it to be a fake? How faithful, or not, do you have to be to the original design to make it a fake?
What arbitrary line shall we draw? Because it is an arbitrary line that has to be drawn with this kind of thinking.
The only objective line that can be drawn is that it is still a genuine coin, with a surface that has been changed (whatever term you might use there).
