Same like Earle42 I recently saw a video as well of someone showcasing their polishing skills on different world coins, no US coins
in the video I watched but would not doubt it.
I imagine reason being, the video is "satisfying". Few million views well worth compromising a rando Kennedy.
Don't be scared of the image optimizer. It will tell you the size of the photos being edited and the threshold you should be within. Just trim 100 width off of the photo until you reach what is acceptable
