No, they aren't ALL overcoated these days. Some are still manufactured without.
And it isn't the glass that is at risk of being scratched, it's the ultra thin layer of Aluminium. It does mark and scratch very easily. Even fingers leave acid on the Aluminium causing oxidisation. The over-coat is meant to slow down the oxidising.
