That's what I'm thinking, a nice brass plate or printed sticker would cover it and look great on the case.If something like acetone or nail varnish remover doesn't touch it then you might be looking at some kind of mechanical removal, when you tried alcohol bit you leave it a while to soak in? sometimes you need to do that & give it a few tries.
You could try an acrylic scratch removal product, normally come in a set of 3 one is almost just a polish, 2 is a light scratch removal & 3 is for deeper scratches.
Other option as has been mentioned is to make a highlight out of it with something like a brass plate or even a printed sticker would do.
